The TPS40042DRCR from Texas Instruments is a low pin count, low VIN synchronous buck DC/DC controller. It is designed to operate with an input voltage range of 3.0V to 5.5V. This controller features voltage mode control and a fixed switching frequency of 600 kHz, simplifying design and reducing external component count.
Key electrical specifications include a maximum output current of 6A and a maximum duty cycle of 95%. The device offers features such as an active low enable, selectable short circuit protection levels, and hiccup restart from faults. It also includes thermal shutdown protection at 145°C.
The TPS40042DRCR is housed in a 10-VSON (3x3 mm) package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. This controller is well-suited for applications like DDR memory, point of load, telecommunications, and DC to DC modules.
Designed for efficiency and ease of use, the TPS40042DRCR integrates high-side drive for N-channel FETs and supports pre-biased outputs. It requires an external reference voltage between 0.5V and 1.5V.
