WD3120 1A output current, fixed 5V Output voltage, Boost Converter with 2.75A Main-Switch Descriptions The WD3120 is a high efficiency, peak current control mode DC-DC boost converter. It supports up to 1A output current with an integrated low RDS(ON) (130m) N-channel MOSFET and cycle by cycle current limit protection. The device provides a USB 5V compliant power output from a single Li-ion battery. The boost converter runs in Pulse-Width Modulation (PWM) mode, at 1MHz fixed switching frequency to reduce output ripple, improve conversion efficiency. It allows for the use of small external components. At light load currents the converter enters Skipping Mode to maintain a high efficiency over a wide load current range.
