Texas Instruments TPSM82830x Step-Down Power Modules
Texas Instruments TPSM82830x Step-Down Power Modules are easy-to-use, synchronous, step-down, DC/DC modules with an integrated inductor and 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 the regulation of the output voltage down to 0.5V with a high feedback voltage accuracy of 1% over the junction temperature range of -40°C to 125°C.
The Texas Instruments TPSM82830x has a MODE pin to control the device's mode of operation. The power save mode maintains high efficiency down to very light loads to extend the system battery run-time. The forced-PWM mode maintains a continuous conduction mode to ensure 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 can operate in 100% mode. The devices incorporate a HICCUP short-circuit protection and a thermal shutdown for fault protection. The family is available in a 3.0mm × 3.0mm × 2.0mm QFN package.
