MIC2165 Adaptive On-Time DC-DC Controller Featuring HyperLight Load® Hyper Speed Control™ Family General Description The Micrel MIC2165 is a synchronous adaptive on-time buck controller targeting high-performance, cost-sensitive applications such as set-top boxes, gateways, routers, computing peripherals, and telecom/networking equipment. The MIC2165 operates over a supply range of 4.5V to 28V. It has an internal linear regulator which provides a regulated 5V supply to power the internal control circuitry. MIC2165 operates at a constant 600kHz switching frequency and can be used to drive up to 25A of output current. The output voltage is adjustable from 0.8V to 5.5V.
