UltraCMOS® Radiation Tolerant Point-of-Load Buck Regulator

The PE99155 is a radiation tolerant point-of-load buck regulator delivering high efficiency at VIN = 5V and output currents up to 10A 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 PE99155 offers excellent power efficiency and intrinsic radiation tolerance.
