The Texas Instruments TPS40190DRCRG4 is a voltage-mode, synchronous buck controller. It is designed to handle an input voltage range from 4.5V to 15V and can deliver up to 20A of output current.
Key electrical specifications include a maximum duty cycle of 85% and a fixed switching frequency of 300 kHz. The controller features enable functionality and pre-bias start-up, along with synchronous rectification for improved efficiency. It also includes selectable short-circuit protection thresholds and an internal 5-V regulator for internal housekeeping and driver power.
This device is housed in a compact 10-VSON (3x3 mm) package with an exposed pad for enhanced thermal performance. The surface mountable design makes it suitable for various electronic applications requiring efficient DC/DC conversion. The operating temperature range is -40°C to 85°C.
Additional features include internal soft start, bootstrapped drivers for N-channel MOSFETs, and adaptive anti-cross conduction. The reference voltage is 0.591V with a ±1% tolerance.
