detailed description operation led current adjustment (iset) tps60230 slvs516a ? may 2004 ? revised june 2004 startup timing figure 11. the tps60230 uses a fractional conversion charge pump to generate a supply voltage for the integrated current sinks. these current sinks are used to ensure a constant current for each led. depending on the input voltage and programmed led current, the charge pump either operates in the 1x mode or in the 1.5x mode. by switching automatically between these two modes, the circuit optimizes power conversion efficiency as well as extends operating time by allowing the discharge of the battery completely. the charge pump can generate 125 ma of output current, so each of the 5 led outputs can be powered with up to 25 ma of current. the maximum led current is set by a resistor connected to the iset pin. this resistor programs a reference current, which is current mirrored to set the led current. applying a pwm signal to the en1 pin and/or the en2 pin controls the led brightness. see a detailed description in the section analog dimming using iset pin. a resistor programs a reference current, which is current mirrored to set the led current. the voltage at the iset pin depends on the status of en1 and en2. the current in each led is typically 260 times the current through the resistor at iset. v iset ? voltage from iset pin (0.2 v, 0.4 v or 0.6 v) to gnd, see table 1 i led ? current per led from dx pin to gnd k ? i set to dx current ratio the led current varies linearly from 0 ma to i led(max) ma by applying a pmw signal with 0% to 100% duty cycle. the led brightness can however also be controlled by an analog control signal that is fed into the iset pin. 9 www .ti.com r i s e t v i s e t i l e d k 100 ma/div 5 v/div e n 1 + e n 2 i i 0 v0 a 1 v/div 0 v vout v i = 3.6 v , i l e d = 20 ma, 5 leds connected,t a = 25 c 20 m s/div
soft start enable (en1, en2) undervoltage lockout short circuit and overtemperture protection overvoltage protection at vout tps60230 slvs516a ? may 2004 ? revised june 2004 detailed description (continued) the tps60230 has an internal soft start circuit to limit the inrush current during startup. this prevents possible voltage drops of the input voltage if a high impedance power source is connected to the input of the tps60230. when the device starts up with an output voltage that is below the input voltage, the output capacitor is charged directly from the input with a current source. the output current increases linearly until the output reaches within 300 mv of the input voltage. when the programmed output current can be reached with the 1x mode, the tps60230 terminates the soft start and begins normal operation. when the desired output current cannot be reached, the charge pump begins operation in 1.5x mode and pumps the output voltage up to the needed level to reach the programmed output current. the enable pins en1 and en2 are used to enable the device or set it into shutdown. the tps60230 is enabled if one of the enable pins is pulled higher than the enable trip point of 1.3 v. the device starts up by going through the soft start routine as described in the section soft start. pulling both pins to gnd, after a delay, programs the device to shutdown. in shutdown, the charge pump, current sources, voltage reference, oscillator, and all other functions are turned off and the supply current is reduced to 0.1 a. en1 and en2 can also be used for dimming. the logic levels at en1 and en2 set the minimum voltage at the current mirrors and the voltage at the iset pin to gnd. this sets the current at the leds to be either the full current or a fraction of the full current. see table 1 for further details. the maximum current through the leds is set by a resistor connected between iset and gnd. en1 and en2 can also be used for pwm dimming. the pwm signal can either be applied to en1 or en2, or both inputs can be tied together and the pwm signal can be applied to both pins. depending on the configuration, the current during pwm dimming is switched between 0 ma and its maximum (en1 and en2 connected to the pwm signal) or between 0 ma and 1/3 of the full led current if en2 = 0 and en1 is toggled. when en1 = 0 and en2 is toggled, the output current can be changed between 0 ma and 2/3 of the full range. table 1. enable levels enable level mode led current en2 en1 0 0 shutdown 0 0 1 viset = 200 mv 1/3 1 0 viset = 400 mv 2/3 1 1 viset = 600 mv full the undervoltage lockout circuit shuts down the device when the voltage at vin drops below a typical threshold of 2.15 v. this prevents damage to the device. the uvlo circuit allows the device to start up again after the voltage on the vin pin has increased by about 100 mv above the uvlo lockout threshold. the current at the vout pin is limited typically to 250 ma. when the junction temperature exceeds 155c, the device shuts down to protect the device from damage. after the temperature decreases to about 135c, the device starts up again if it is enabled. the device uses the voltage at d1 to regulate voltage at vout. in case d1 is not connected, an overvoltage protection circuit ensures that the output voltage at vout does not exceed its limits. the connection of the leds must be started using d1 first. for all other leds there is no restriction in the sequence. for example, if there are only 3 leds used, the first led is connected to d1 and the other two leds can be connected to any other of the d2 to d5 pins. 10 www .ti.com
theory of operation/design procedure capacitor selection power efficiency power dissipation tps60230 slvs516a ? may 2004 ? revised june 2004 ceramic capacitors such as x5r or x7r are recommended to be used with the tps60230. for the two flying capacitors c1 and c2, it is important to use low esr capacitors to avoid unnecessary efficiency losses. low esr capacitors on vout reduce the ripple voltage on the supply of the current sources. table 2 lists capacitor types that have been tested with the tps60230. table 2. capacitors part value voltage manufacturer size website c1608x5r1a105m 1 mf 10 v 0603 c1608x5r1a474m 0.47 mf 10 v tdk 0603 www.componnent.tdk.com c2012x7r1c105m 1m f 16 v 0805 lmk107bj105ma 1 mf 10 v 0603 lmk107bj474ma 0.47 mf 10 v taiyo yuden 0603 www.t-yuden.com lmk212bj105mg 1m f 10 v 0805 the power conversion efficiency of the tps60230 can be calculated by adding up the products of each led current and voltage and dividing it by the product of the input voltage and current. with a fully charged battery where the input voltage is typically above the led forward voltage, the charge pump operates in the 1x mode and efficiency is very high. as the battery discharges, there is a point where the current sources no longer have enough voltage overhead to maintain a constant current regulation. at that point, the charge pump switches into the 1.5x mode. the conversion efficiency is lowest at the crossover. as the battery discharges further, the efficiency again increases until at about 3.1 v where it reaches a second maximum. below 3.1 v input voltage, the maximum current per led is less than 25 ma. the maximum power dissipation inside the tps60230 can be calculated based on the following equation: p d max = [(1.5 v i ) ? v o + 0.4 v] i o the maximum power dissipation occurs when the input voltage is just low enough to operate in 1.5x mode, with a forward voltage of the white led at maximum. this is typically for v i = 4.2 v and a forward voltage of 3.6 v. this needs to be lower than the maximum allowed power dissipation of the package, which can be calculated using the following equation: for example, the worst case power dissipation occurs at the input voltage level where the charge pump switches from the 1x mode to the 1.5x mode. at this operating point, the supply voltage to the current sources is at its maximum and the current sources must drop the most voltage in order to maintain a regulated output current. the worst case power dissipation occurs when all 5 led outputs are fully loaded with 25 ma of led current. with: v i = 4.2 v, v f = 3.6 v, i o = 125 ma (1.5x mode) p d max = 0.39 w 11 www .ti.com p d m a x , p a c k a g e t j m a x t a t j a
