PE99153 fiche technique
Product Description
The PE99153 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.
