TPS51313DRCR

TPS51313 is an easy-to-use, fully integrated, synchronous buck converter designed for low-voltage point-of-load applications. It is designed to comply with the NVIDIA OpenVreg Type 0 specification, including requirements for package type and package dimensions. It supports a 3A (maximum) DC output current at output voltages between 0.6V and 3.3V. D-CAP2 mode adaptive, constant on-time control (1MHz switching frequency) enables small package size and low external component count when designing with all-ceramic output capacitors. The device also features automatic skip mode under light load conditions, pre-bias startup, and an internal fixed soft-start time. When the device is disabled, the output capacitor is discharged through an internal resistor. The TPS51313 is available in a 3mm × 3mm, 10-pin DRC package (RoHS compliant and lead-free), rated for a temperature range of -10°C to 85°C.
