Product 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 component
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 Peregrineâs patented UltraCMOS®
technology, the PE99151 offers excellent power
efficiency and intrinsic radiation tolerance.
