TPS65320C-Q1 Description

Short technical summary and product information.

The TPS65320C-Q1 from Texas Instruments is a versatile power management integrated circuit designed for automotive applications. It combines a high-input voltage DC-DC step-down buck converter with an adjustable switching frequency from 100 kHz to 2.5 MHz, capable of delivering up to 3.2 A. This buck regulator operates with an input range of 3.6 V to 36 V and an adjustable output from 1.1 V to 20 V.

 

Complementing the buck converter is a high-VIN 280 mA low-dropout (LDO) regulator. The LDO features an input range of 3 V to 20 V and can auto-source from the buck regulator's output for efficiency. It provides a typical quiescent current of 45 µA in no-load conditions and a low-dropout voltage of 300 mV at 200 mA.

 

This device is AEC-Q100 qualified, with a temperature grade of 1 (-40°C to +125°C ambient operating temperature). It includes features such as overcurrent protection, overtemperature protection, and a power-good output. The TPS65320C-Q1 is available in a 14-pin HTSSOP package with PowerPAD™ for enhanced thermal performance, suitable for surface mounting.

 

Note: This product is not recommended for new designs.
