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. The build-in soft start circuitry
minimizes the inrush current at start-up. Fixed 5V
output and internal compensation network require only
boost inductor, schottky diode, and input and output
capacitors for WD3120, save PCB area.
The WD3120 is available in SOT-23-6L package.
Standard product is Pb-free and Halogen-free.
