TPS65321AQPWPRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS65321AQPWPRQ1 is a versatile power management IC designed for automotive applications. It integrates a high-VIN DC-DC step-down (buck) converter with an adjustable switching frequency from 100 kHz to 2.5 MHz, capable of delivering up to 3.2A. This buck regulator operates from an input voltage range of 3.6V to 36V and provides an adjustable output voltage from 1.1V to 20V.

 

Complementing the buck converter is a high-VIN 280mA low-dropout (LDO) voltage regulator, which accepts an input voltage from 3V to 36V. The LDO features a low quiescent current of 35µA (typical) at no load and a low-dropout voltage of 300mV at 200mA output current.

 

Both regulators include overcurrent and overtemperature protection. The device is housed in a 14-pin HTSSOP package with PowerPAD, suitable for surface mounting. It is AEC-Q100 qualified for automotive temperature grade 1 operation (-40°C to +125°C).

 

Key features include high efficiency at light loads with Eco-mode™ control, reset output pin, and synchronization to an external clock. This combination makes the TPS65321AQPWPRQ1 suitable for various automotive power supply designs.
