Description

The TPS6282x is an easy-to-use synchronous step-down DC-DC converters family with a very low quiescent current of only 4 µA. Based on the DCS-Control topology, it provides a fast transient response. The internal reference allows to regulate the output voltage down to 0.6 V with a high feedback voltage accuracy of 1% over the junction temperature range of –40°C to 125°C. The family devices are pin-to-pin and BOM-to-BOM compatible. The entire solution requires a small 470-nH inductor, a single 4.7-µF input capacitor and two 10-µF or single 22-µF output capacitor.

The TPS6282x is available in two flavors. The first includes an automatically entered power save mode to maintain high efficiency down to very light loads for extending the system battery run-time. The second runs in forced-PWM maintaining a continuous conduction mode to ensure the least ripple in the output voltage and a quasi-fixed switching frequency. The device features a Power Good signal and an internal soft start circuit. It is able to operate in 100% mode. For fault protection, it incorporates a HICCUP short circuit protection as well as a thermal shutdown. The device is available in a 6-pin 1.5 x 1.5-mm QFN package, offering the highest power density solution.
