TPS62142RGTR

3 V至17 V 2 -A降压转换器在3毫米？ 3毫米QFN封装 3-V to 17-V 2-A Step-Down Converter in 3-mm × 3-mm QFN Package

DESCRIPON

The TPS6214X family is an easy-to-use synchronous step-down dc-dc converter optimized for applications with high power density. A high switching frequency of typically 2.5MHz allows the use of small inductors and provides fast transient response by use of the DCS-Control™ topology.

With its wide operating input voltage range of 3V to 17V, the devices are ideally suited for systems powered from either a Li-Ion or other batteries, as well as from 12-V intermediate power rails. It supports up to 2A of continuous output current at output voltages between 0.9V and 6V with 100% duty-cycle mode.
