TPS62130RGTT Step-Down Converter Description
The TPS62130 is a simple to use synchronous step-down DC-DC converter designed for high power density applications. By utilizing the DCS-Control topology, a high switching frequency of typically 2.5 MHz allows the use of small inductors and provides a fast transient response as well as high output voltage accuracy.
The device's wide operating input voltage range of 3 V to 17 V makes it ideal for systems powered by Li-Ion or other batteries, as well as 12-V intermediate power rails. It can deliver up to 3-A continuous output current at output voltages ranging from 0.9 V to 6 V. (with 100 percent duty cycle mode). The soft-start pin controls the output voltage start-up ramp, allowing it to operate as a stand-alone power supply or in tracking configurations. By configuring the Enable and open-drain Power Good pins, power sequencing is also possible.
