Buck controllers regulate output from 0.8 to 7 V

Buck controllers regulate output from 0.8 to 7 V

The ADP1882 and ADP1883 synchronous current-mode buck controllers provide superior transient response through the use of a constant on-time, valley-current-mode control system. They drive all n-channel power stages to regulate output voltages as low as 0.8 V with ±1.0% accuracy to as high as 7 V with output up to 15 A. They use input-power voltages ranging from 2.75 to 20 V.

These buck controllers suit intermediate rail or PoL generation in consumer, industrial instrumentation, telecommunications, and networking applications. Each device is available in 300-kHz, 600-kHz, and 1-MHz frequencies. They feature an internally fixed soft-start period that enables a limited input in-rush current from the input supply during startup, a reverse-current protection during soft-start providing a precharged output, and thermal overload and short-circuit protection. The ADP1883 also offers pulse skipping to maintain output regulation while improving system efficiency at light loads. ($1.03 ea/1,000 available now.)
