The TPS40193DRCRG4 from Texas Instruments is a voltage-mode synchronous buck controller. It is designed to operate with an input voltage range of 4.5V to 18V and can support output currents up to 20A. The device features a switching frequency of 300kHz, making it suitable for various power management applications.
Key electrical features include a maximum duty cycle of 85% and a typical quiescent current of 0.0025A. The controller supports essential control functions such as Enable and Power Good signals, along with pre-bias startup and synchronous rectification. It also incorporates internal protection mechanisms like thermal shutdown at 145°C and selectable short-circuit protection levels.
The TPS40193DRCRG4 is housed in a 10-pin VSON package with exposed pad dimensions of 3mm x 3mm, designed for surface mounting. The operating temperature range is specified from -40°C to 85°C (TA). This controller is part of the TPS4019x family, offering robust performance for DC/DC conversion needs.
