TPS65321-Q1 - Texas Instruments

TPS65321-Q1 36-V Step-Down Converter

The TPS65321-Q1 device is a combination of a highVIN DC-DC step-down converter, referred to as the buck regulator, with an adjustable switch-mode frequency from 100-kHz to 2.5-MHz, and a high-VIN 280-mA low-dropout (LDO) regulator. The input range is 3.6 V to 36 V for the buck regulator, and 3 V to 36 V for the LDO regulator. The buck regulator has an integr.
