AP63300WU-7

AP63300WU-7 is a synchronous buck converter. The device fully integrates a 75mohm high-side power MOSFET and a 40mohm low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The design is optimized for electromagnetic interference (EMI) reduction. The device has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces high-frequency radiated EMI noise caused by MOSFET switching. It also features frequency spread spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. Applications include 5V, 12V, and 24V distributed power bus supplies, flat screen TV sets and monitors, power tools and laser printers, white goods and small home appliances, FPGA, DSP, and ASIC supplies, home audio, network systems, gaming consoles, consumer electronics, and general-purpose point of load.
