PE99155 - Peregrine Semiconductor

PE99155 Hi-Rel 10A DC-DC Converter

The PE99155 is a radiation tolerant point-of-load buck regulator delivering high efficiency at VIN = 5V and output currents up to 10A continuous. This single-chip solution is perfect for Hi-Rel applications and delivers peak efficiency exceeding 93%. A minimal external component count and high switching frequency enables >10 W/in2 standard PCB designs while .
