The Texas Instruments TPS40200HDR is a high-temperature DC DC switching controller designed for demanding applications. It features a wide input voltage range from 5.5V to 52V and supports an operating temperature range of -55°C to 175°C.
This non-synchronous buck controller offers features such as voltage feed-forward compensation, undervoltage lockout, and programmable fixed-frequency operation between 35 kHz and 500 kHz. It also includes programmable short-circuit protection with hiccup overcurrent fault recovery and programmable closed-loop soft start.
The TPS40200HDR is housed in an 8-SOIC package and is suitable for surface mount applications. Its design is optimized for high-temperature environments, making it ideal for applications such as down-hole drilling and other extreme temperature scenarios.
Key electrical characteristics include a 700mV reference voltage with 1% accuracy and an internal 200mA P-channel FET driver. The device supports external synchronization and provides a positive output configuration.
