The SP7663 is a synchronous voltage mode PWM step-down (buck) regulator capable of a constant output current up to 6A. A wide 5V to 22V single input voltage range allows for single supply operations from industry standard 5V, 12V and 18V power rails. Operations down to 3V are supported with an additional biasing voltage.

With a 600kHz constant operating frequency and integrated high and low side switch, the SP7663 reduces the overall component count and solution footprint. In addition to a 1% output set point accuracy, this device provides high efficiency, low ripple and excellent line and load regulation. An enable function and soft-start feature allow for controlled power up sequencing implementation.

Built-in current limiting, UVLO, output short-circuit and over temperature protection ensure safe operation under abnormal operating conditions.

The SP7663 is offered in a RoHS compliant, lead free 26-pin 7mm x 4mm DFN package.

  • 4.5V to 5.5V or 4.75V to 22V input voltage range using single supply
