Texas Instruments TPS54561QDPRRQ1

The TPS54561-Q1 device is a 60-V, 5-A, step-down regulator with an integrated high-side MOSFET. The device survives load dump pulses up to 65 V per ISO7637. Current-mode control provides simple external compensation and flexible component selection. A low-ripple pulse-skip mode and 152-µA supply current enables high efficiency at light loads. Pulling the enable pin low reduces shutdown supply current to 2 µA.

Undervoltage lockout has an internal 4.3-V setting. Use of an external resistor divider at the EN pin can increase the setting. The soft-start pin controls the output-voltage start-up ramp and also configures sequencing or tracking. An open-drain power-good signal indicates the output is within 93% to 106% of its nominal voltage.

A wide adjustable switching-frequency range allows optimization for either efficiency or external component size. Cycle-by-cycle current limit, frequency foldback, and thermal shutdown protect the device during an overload condition.

The TPS54561-Q1 is available in a 10-pin, 4-mm × 4-mm WSON package.
