    Power Management - DC2DC GROUP

The WD3136E is a high efficiency, high power, peak current mode step-up converter integrated 32V power MOSFET with 3A (Typ.) current limit. It could support up to maximum 24V output.

The boost converter WD3136E runs in Pulse-Width Modulation (PWM) mode at 1 MHz fixed switching frequency to reduce output ripple and improve conversion efficiency. It allows for the use of small external components. At light load, 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 WD3136E is available in SOT-23-6L package. Standard product is Pb-free and Halogen-free.
