LP6202A
Synchronous Boost DC/DC Regulator
General Description
The LP6202A is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficiency solution to medium power system. the devices work under the input voltage between 0.9V and 4.4V with a 1.4 MHz fixed frequency switching. These features minimize overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
Features
Up to 94% efficiency Low voltage start-up:0.9V Shut-down current:<1uA
Output voltage:2.5-4.3V(Up to 5V with schottky) Low switch on resistance RDS(ON),Internal switch:0.35 OHM
High switch on current:1A 1.4MHz fixed frequency switching
Available in SCT23-6 Package
