ADI LTC3879IUD#PBF

降压降压4V ~ 38V

Overview

The LTC3879IUD is a synchronous step-down switching regulator controller optimized for high switching frequency and fast transient response. The constant on-time valley current mode architecture allows for a wide input range, including very low duty factor operation. No external sense resistor or slope compensation is required. System flexibility is offered through a user-programmable soft-start pin and independent RUN pin. The voltage ramping soft-start function can be programmed with a capacitor or made to track an external reference source.

The LTC3879IUD allows operation from 4V to 38V at the input and from 0.6V to 90% VIN at the output. The LTC3879IUD is available in a small 16-pin thermally enhanced MSOP or 3mm × 3mm QFN packages.
