PE99151
Description
The PE99151 is a radiation tolerant point-of-load buck regulator delivering high efficiency at VIN = 5V and output currents up to 2A 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. All power switching devices are integrated on-chip.
Fabricated in Peregrine’s patented Ultra CMOS® technology, the PE99151 offers excellent power efficiency and intrinsic radiation tolerance.
