TPS40190DRCR Description

Short technical summary and product information.

The Texas Instruments TPS40190DRCR is a voltage-mode, synchronous buck controller. It is designed to operate with an input voltage range of 4.5V to 15V and can deliver up to 20A of output current. The controller features a fixed switching frequency of 300 kHz, which aids in efficient power conversion.

 

Key electrical characteristics include a selectable short-circuit protection threshold, internal soft start, and an internal 5V regulator for housekeeping functions. The device supports pre-bias start-up and utilizes bootstrapped drivers for N-channel MOSFETs, contributing to decreased switching loss. Its adaptive anti-cross conduction feature enhances operational reliability.

 

The TPS40190DRCR is housed in a compact 10-VSON (3x3 mm) package, suitable for surface mount applications. The operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. This controller is a robust solution for DC/DC step-down conversion needs.
