The TPS62830x is an easy-to-use, synchronous, step-down, DC/DC converters family with low quiescent current. Based on the DCS-Control topology, TPS62830x provides a fast transient response with small output capacitance. The internal reference allows to regulate 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 family is available in two packages and each package devices are pin-to-pin compatible.
The TPS62830x 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 device features a Power-Good signal and a well-controlled internal soft-start circuit. TPS62830x is able to operate in 100% mode. For fault protection, TPS62830x incorporates a HICCUP short-circuit protection as well as a thermal shutdown. One device option has a latch-off protection for short circuit as well as overvoltage incidents. The family is available in two packages: an 8-pin 1.0mm × 2.0mm QFN package, offering the highest power density design, and an 8-pin 1.6mm × 2.1mm SOT583 package, offering an easy-to-assemble designs.
