The TPS40040DRBT from Texas Instruments is a low pin count, synchronous buck DC-to-DC controller. It is designed to operate from a 2.25-V to 5.5-V input source, making it suitable for various power management applications.
Key electrical specifications include a switching frequency of 300 kHz, a maximum duty cycle of 95%, and a reference voltage of 0.6V. The controller supports an output voltage range from 0.6 V to 90% of VIN and features selectable short circuit protection levels of 105 mV, 180 mV, and 310 mV. It also includes an active low enable feature and thermal shutdown protection at 145°C.
This controller is housed in an 8-pin SON (3x3) package with an exposed pad for improved thermal performance. The mounting type is surface mount, and it is designed for applications such as point-of-load, telecommunications, DC to DC modules, and set-top boxes.
