WD3133
HIGH EFFICIENCY, 1.2-MHz 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 1.2MHz 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.
The WD3133 is available in SOT-23-5L package.
Standard product is Pb-free and Halogen-free.
Features
Wide input voltage range from 2.7-V to 5.5-V
1.25-V (±2%) high accuracy reference voltage
1.2-MHz switching frequency
Up to 93% efficiency
Over 1-A (min.) power switch current limit
Provide typical 12V / 200mA~300mA output from
3.3V~5V input
Built-in Soft-Start
Applications
Smart Phones
Tablets
Portable games
