www.austriamicrosystems.co m/dc-dc_step-down/as1346 revision 1.01 10 - 15 as1346, as1347, AS1348, as1349 datasheet - detailed description when the top mosfet is off, the bottom mosfet is turned on until the inductor current starts to reverse as indicated by the current reversal comparator, or the next clock cy cle begins. the over-voltage detection comparator guards against transient overshoots >7.8% by turning the main switch off and keeping it off until the transient is removed. short-circuit protection the short-circuit protection turns off the power switches as long as the short is applied. when the short is removed the device is continuing normal operation. dropout operation the as1346, as1347, AS1348, as1349 is working with a low input-to-output voltage difference by operating at 100% duty cycle. in this state, the pmos is always on. this is pa rticularly useful in battery-powered applications with a 3.3v output. the as1346, as1347, AS1348, as1349 allows the output to follow the input battery voltage as it drops below the reg- ulation voltage. the quiescent current in this state is reduc ed to a minimal value, which aids in extending battery life. this dropout (100% duty-cycle) operation achieves long batter y life by taking full advantage of the entire battery range. the input voltage requires maintaining regulation and is a function of the output voltage and the load. the difference between the minimum input voltage and the output voltage is called the dropout voltage. the dropout voltage is there- fore a function of the on-resistance of the internal pmos (r ds(on)pmos ) and the inductor resistance (dcr) and this is proportional to the load current. note: at low v in values, the r ds(on) of the p-channel switch increases (see electrical characteristics on page 4) . therefore, power dissipation should be taken in consideration. shutdown connecting en to gnd or logic low places the as1346, as1347, AS1348, as1349 in shutdown mode and reduces the supply current to 0.1a. in shutdown the control circuitry and the internal nmos and pmos turn off and sw becomes high impedance disconnecting the input from the output. the output capacitance and load current determine the volt- age decay rate. for normal operation connect en to v in or logic high. note: pin en should not be left floating. power-ok and low-battery-detect functionality lbo goes low in startup mode as well as during normal operation if: - the voltage at the lbi pin is below lbi threshold (1.2v). this can be used to monitor the battery voltage. - lbi pin is connected to gnd and v out1 is below 92.5% of its nominal value. lbo works as a power-ok signal in this case. the lbi pin can be connected to a resistive-divider to monitor a particular definable voltage and compare it with a 1.2v internal reference. if lbi is connected to gnd (see figure 1 on page 1) an internal resistive-divider is activated and connected to the output. therefore, the power-ok func tionality can be realised with no additional external components. the power-ok feature is not active during shutdown. to obtain a logic-level output, connect a pull-up resistor from pin lbo to pin v out or v dd . larger values for this resistor will help to minimize current consumption; a 100k resistor is perfect for most applications (see figure 18 on page 11) . for the circuit shown in the left of figure 18 on page 11 , the input bias current into lbi is very low, permitting large- value resistor-divider networks while maintaining accuracy. place the resistor-divider network as close to the device as possible. use a defined resistor for r 2 and then calculate r 1 as: where: v lbi (the internal sense reference voltage) is 1.2v.
