Preliminary Datasheet
LP6343
1.
5MHz, 3A Step-down Converter With Soft-Start
General Description
The LP6343 contains a independent 1.
5MHz constant frequency, current mode, PWM step-down converters.
The converter integrates a main switch and a synchronous rectifier for high efficiency without an external
Schottky diode.
The LP6343 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery.
The converter can supply 3000mA of load current from a 2.
5V to 5.
5V input voltage.
The output voltage can be regulated as low as 0.
6V.
The LP6343 can also run at 100% duty cycle for low dropout applications.
The LP6343 is available in a 10-lead 3mm*3mm TDFN-10 and EMS...
