PE99153DIE Overview
The PE99153 DIE is a radiation tolerant point-of-load buck regulator delivering high efficiency at VIN = 5V and output currents up to 6A continuous. This single-chip solution is perfect for Hi-Rel applications and delivers peak efficiency exceeding 93%. A minimal external ponent count and high switching frequency enables >10 W/in2 standard PCB designs while high efficiency minimizes thermal concerns.
