tps62085 TPS62086 tps62087 www.ti.com slvsb70 ? october 2013 detailed description device operation the tps62085, TPS62086, and tps62087 synchronous step-down converters are based on the dcs-control (direct control with seamless transition into power save mode) topology. this is an advanced regulation topology that combines the advantages of hysteretic, voltage, and current mode control schemes. the dcs-control topology operates in pwm (pulse width modulation) mode for medium to heavy load conditions and in power save mode at light load currents. in pwm mode, the converter operates with its nominal switching frequency of 2.4 mhz having a controlled frequency variation over the input voltage range. as the load current decreases, the converter enters power save mode, reducing the switching frequency and minimizing the ic quiescent current to achieve high efficiency over the entire load current range. since dcs-control supports both operation modes (pwm and pfm) within a single building block, the transition from pwm mode to power save mode is seamless and without effects on the output voltage. fixed output voltage version provides smallest solution size combined with lowest quiescent current. the devices offer both excellent dc voltage and superior load transient regulation, combined with very low output voltage ripple, minimizing interference with rf circuits. power save mode as the load current decreases, the tps62085, TPS62086, and tps62087 enter power save mode operation. during power save mode, the converter operates with reduced switching frequency and with a minimum quiescent current maintaining high efficiency. the power save mode occurs when the inductor current becomes discontinuous. it is based on a fixed on-time architecture, following equation 1 . the switching frequency over the whole load current range is also shown in figure 9 for a typical application. (1) in power save mode, the output voltage rises slightly above the nominal output voltage, as shown in figure 8 . this effect is minimized by increasing the output capacitor or inductor value. the output voltage accuracy in pfm operation is reflected in the electrical specification table and given for a 22- f output capacitor. 100% duty cycle low dropout operation the devices offer low input to output voltage difference by entering 100% duty cycle mode. in this mode the high side mosfet switch is constantly turned on and the low side mosfet is switched off. this is particularly useful in battery powered applications to achieve the longest operation time by taking full advantage of the whole battery voltage range. the minimum input voltage to maintain output regulation, depending on the load current and output voltage can be calculated as: (2) with: v in,min = minimum input voltage to maintain an output voltage i out,max = maximum output current r ds(on) = high side fet on-resistance r l = inductor ohmic resistance (dcr) enable / disable the devices are enabled by setting the en pin to a logic high. accordingly, shutdown mode is forced if the en pin is pulled low with a shutdown current of typically 0.7 a. in shutdown mode, the internal power switches as well as the entire control circuitry are turned off. an internal resistor of 260 discharges the output via the vos pin smoothly. the output discharge function also works when thermal shutdown, undervoltage lockout or short circuit protection are triggered. copyright ? 2013, texas instruments incorporated submit documentation feedback 9 product folder links: tps62085 TPS62086 tps62087 in,min out out,max ds(on) l v v i (r + r ) = + l v v v v t i2 f v v ns 420 t out in out in 2 on out pfm in out on - = =
tps62085 TPS62086 tps62087 slvsb70 ? october 2013 www.ti.com an internal pull-down resistor of 400 k is connected to the en pin when the en pin is low. the pull-down resistor is disconnected when the en pin is high. soft start the tps62085, TPS62086, and tps62087 have an internal soft start circuitry which monotonically ramps up the output voltage and reaches the nominal output voltage during a soft start time of typical 0.8 ms. this avoids excessive inrush current and creates a smooth output voltage slope. it also prevents excessive voltage drops of primary cells and rechargeable batteries with high internal impedance. the device is able to start into a pre- biased output capacitor. the device starts with the applied bias voltage and ramps the output voltage to its nominal value. switch current limit and hiccup short circuit protection the switch current limit prevents the devices from high inductor current and from drawing excessive current from the battery or input voltage rail. excessive current might occur with a shorted/saturated inductor or a heavy load/shorted output circuit condition. if the inductor current reaches the threshold i lim , the high-side mosfet is turned off and the low-side mosfet is turned on to ramp down the inductor current. once this switch current limits is triggered 32 times, the devices stop switching and enables the output discharge. the devices then automatically start a new startup after a typical delay time of 66 s has passed. this is named hiccup short circuit protection. the devices repeat this mode until the high load condition disappears. power good the tps62085, TPS62086, and tps62087 have a power good output. the power good goes high impedance once the output is above 95% of the nominal voltage, and is driven low once the output voltage falls below typically 90% of the nominal voltage. the pg pin is an open drain output and is specified to sink up to 1 ma. the power good output requires a pull-up resistor connecting to any voltage rail less than 6 v. the power good goes low when the devices are disabled or in thermal shutdown. when the devices are in uvlo, the pg pin is high impedance. the pg signal can be used for sequencing of multiple rails by connecting it to the en pin of other converters. leave the pg pin unconnected when not used. under voltage lockout to avoid mis-operation of the device at low input voltages, an under voltage lockout is implemented, which shuts down the devices at voltages lower than v uvlo with a hysteresis of 200 mv. thermal shutdown the device goes into thermal shutdown and stops switching once the junction temperature exceeds t jsd . once the device temperature falls below the threshold by 20 c, the device returns to normal operation automatically. 10 submit documentation feedback copyright ? 2013, texas instruments incorporated product folder links: tps62085 TPS62086 tps62087

tps62085 TPS62086 tps62087 slvsb70 ? october 2013 www.ti.com the architecture of the tps62085, TPS62086, and tps62087 allows the use of tiny ceramic output capacitors with low equivalent series resistance (esr). these capacitors provide low output voltage ripple and are recommended. to keep its low resistance up to high frequencies and to get narrow capacitance variation with temperature, it is recommended to use x7r or x5r dielectrics. the recommended typical output capacitor value is 22 f and can vary over a wide range as outline in the output filter selection table. setting the output voltage the output voltage is set by an external resistor divider according to the following equation: (4) r2 should not be higher than 180 k to achieve high efficiency at light load while providing acceptable noise sensitivity. lowest operating quiescent current and best output voltage accuracy are achieved with the fixed output voltage versions. for the fixed output voltage versions, the fb pin must be connected to the output. pcb layout recommendation the pcb layout is an important step to maintain the high performance of the tps62085, TPS62086, and tps62087 devices. the input/output capacitors and the inductor should be placed as close as possible to the ic. this keeps the traces short. routing these traces direct and wide results in low trace resistance and low parasitic inductance. the low side of the input and output capacitors must be connected directly to the gnd pin to avoid a ground potential shift. the sense traces connected to fb and vos pins are signal traces. special care should be taken to avoid noise being induced. by a direct routing, parasitic inductance can be kept small. gnd layers might be used for shielding. keep these traces away from sw nodes. see figure 22 for the recommended pcb layout. figure 22. pcb layout recommendation thermal information implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires special attention to power dissipation. many system-dependent issues such as thermal coupling, airflow, added heat sinks and convection surfaces, and the presence of other heat-generating components affect the power- dissipation limits of a given component. two basic approaches for enhancing thermal performance are listed below: ? improving the power dissipation capability of the pcb design ? introducing airflow in the system 12 submit documentation feedback copyright ? 2013, texas instruments incorporated product folder links: tps62085 TPS62086 tps62087 1 vout vin gnd c1 c2 l1 r1 r2 ? ? ? ? + = ? ? ? ? + = 2r 1r 1 v8.0 2r 1r 1 v v fb out
