AP63205WU-7

AP63205WU-7 is a synchronous buck converter with enhanced EMI reduction. It has a wide input voltage range of 3.8V to 32V and fully integrates a 125mohm high-side power MOSFET and a 68mohm low side power MOSFET to provide high-efficiency step-down DC/DC conversion. It is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated compensation network. It has optimized designs for electromagnetic interference (EMI) reduction. The converter features a 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. Application includes 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, set top boxes, gaming consoles, consumer electronics.
