The TPSM82830x is an easy-to-use, synchronous, step-down, DC/DC module family with integrated inductor and integrated on-chip noise-filtering capacitors. Based on the DCS-Control topology, the devices provide a fast transient response with small output capacitance. The internal reference allows to regulate the output voltage down to 0.5 V with a high feedback voltage accuracy of 1% over the junction temperature range of –40°C to 125°C.

The TPSM82830x has a MODE pin to control the device mode of operation. Power save mode maintains high efficiency down to very light loads for extending the system battery run-time. Forced-PWM mode maintains a continuous conduction mode to make sure the least ripple in the output voltage and a quasi-fixed switching frequency. The devices feature a Power-Good signal and a well-controlled internal soft-start circuit. The devices are able to operate in 100% mode. For fault protection, the devices incorporate a HICCUP short-circuit protection as well as a thermal shutdown. The family is available in a 3.0-mm × 3.0-mm × 2.0-mm QFN package.
