WD3133 HIGH EFFICIENCY, 1.2-MH- DC-DC STEP-UP CONVERTERS Descriptions The WD3133 is a high efficiency, high power, peak current mode step-up converter. Internal 0.35Ω HV power MOSFET with Min. 1A current limit. For portable device with Li-ion battery application, WD3133 could output typical 12V , 200mA ~300mA from 3.3V~5V input. The boost converter WD3133 runs in Pulse-Width Modulation (PWM) mode, at 1.2MH- fixed switching frequency to reduce output ripple, improve conversion efficiency. It al
