The TPS40042DRCT from Texas Instruments is a synchronous buck DC-to-DC controller designed for applications requiring a 3.0V to 5.5V input voltage. This controller features a fixed internal switching frequency of 600 kHz, simplifying design and reducing external component count.
Key electrical features include an external reference requirement of 0.5V to 1.5V, with the output voltage adjustable from the reference input up to 90% of VIN. It supports pre-biased outputs and includes adaptive anti-cross conduction gate drive for efficient operation. The device offers three selectable short circuit protection levels and hiccup restart from faults for robust performance.
For thermal management, the TPS40042DRCT includes thermal shutdown protection at 145°C. It also features an active low enable pin. The controller is housed in a 10-pin VSON package with a 3mm x 3mm footprint, suitable for surface mounting.
Applications for the TPS40042DRCT include DDR memory power, point-of-load supplies, telecommunications equipment, and general DC-to-DC modules.
