TPS40200HD Description

Short technical summary and product information.

The TPS40200HD from Texas Instruments is a high-temperature, wide-input, non-synchronous buck DC/DC controller designed for demanding environments. This device operates across a broad input voltage range of 5.5V to 52V, making it suitable for various power supply applications.

 

Key electrical specifications include a maximum output current capability of 3A and a configurable switching frequency ranging from 35kHz to 500kHz. The controller utilizes a voltage mode control architecture and supports a maximum duty cycle of 90% (or 98% as per fetched data). It features programmable soft-start and short-circuit protection, along with hiccup mode for overcurrent fault recovery.

 

Designed for extreme conditions, the TPS40200HD boasts an impressive operating temperature range of -55°C to 210°C. It is available in an 8-SOIC package and supports surface mount installation. This controller is particularly well-suited for applications requiring high reliability in high-temperature environments, such as down-hole drilling equipment.

 

Additional features include undervoltage lockout, voltage feed-forward compensation, and an internal 200-mA P-channel FET driver. The 700-mV reference voltage and external synchronization capability provide design flexibility.
