PE99153DIE Datasheet, PDF (1/15 Pages) Peregrine Semiconductor – Hi-Rel 6A DC-DC Converter

Product Description
The PE99153 DIE is a radiation tolerant point-of-load
buck regulator delivering high efficiency at V_IN = 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.
