Product Description
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 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 Peregrine’s patented UltraCMOS® technology, the PE99153 offers excellent power efficiency and intrinsic radiation tolerance.
