The PE99155 is a radiation hardened point-of-load buck regulator delivering high efficiency at V IN =5V and output currents up to 10A. This single-chip solution is suited for Hi-Rel applications and delivers peak efficiency exceeding 93%. A minimal external component count and high switching frequency enables > 10 W/in 2 standard PCB designs while high efficiency minimizes thermal concerns. All power switching devices are integrated on-chip. Fabricated using Peregrine?s patented UltraCMOS ? technology, the PE99155 offers excellent power efficiency and intrinsic radiation tolerance. ????????????????????????????????
