Preliminary Datasheet LP6202 Synchronous Boost DC/DC Regulator General Description Features The LP6202 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. □ □ 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 Ordering Information LP6202 - Up to 94% efficiency Available in SCT23-6 Package □ F: Pb-Free Pin Configurations Package Type B6: SOT23-6 Typical Application Circuit Vin(0.9V-5V) 2.2uH Vout_5V/600mA 1 + 6 SW 47uF Vin SOT23-6 OUT 5 + 4 EN R3 100K R1 1.5M FB Cout 100uF 3 R2 500K 2 ON/OFF GN D LP6202 Applications Marking Information AlK.
