FP6396 Description
The FP6396 is a high efficiency, high frequency synchronous DC-DC step-down converter. The 100% duty cycle feature provides low dropout operation, extending battery life in portable systems.
The internal synchronous switch increases efficiency and eliminates the need for external schottky diode. At shutdown mode, the input supply current is less than 1µA.
The FP6396 fault protection includes over current protection, short circuit protection, UVLO and thermal shutdown. The Internal soft-start function prevents inrush current at turn-on.
The FP6396S5 uses in SOT-23-5 packages.

Details
The FP6396 is a high efficiency, internal compensation and constant frequency current mode step-down synchronous DC/DC converter. It has integrated high-side (340mΩ, typ.) and low-side (210mΩ, typ.) power switches, and provides 1.2A continuous load current. It regulates input voltage from 2.5V to 6V, and down to an output voltage as low as 0.6V.
Enable
The FP6396 EN pin provides digital control to turn on/off the regulator. When the voltage of EN exceeds the threshold voltage, the regulator will start the soft start function. If the EN pin voltage is below the shutdown threshold voltage, the regulator will turn into the shutdown mode and the shutdown current will be smaller than 1μA. For auto start-up operation, connect EN to VIN.
Soft Start
The FP6396 employs internal soft start function to reduce input inrush current during start up. The internal soft start time will be 1ms.
Under Voltage Lockout
When the FP6396 is power on, the internal circuits will be held inactive until VIN voltage exceeds the UVLO threshold voltage. And the regulator will be disabled when VIN is below the UVLO threshold voltage. The hysteretic of the UVLO comparator is 200mV (typ).
Input Over Voltage Protection
The FP6396 supports input over voltage protection. When input voltage exceeds the input over voltage threshold, the regulator will be shutdown unless the input over voltage is removed.
