The XRP7657 is a non synchronous voltage mode PWM step down (buck) regulator capable of a constant output current up to 2Amps. A wide 4.75V to 25V input voltage range allows for single supply operations from industry standard 5V, 12V and 24V power rails.
With a 420kHz constant operating frequency and integrated high side switch, the XRP7657 reduces the overall component count and solution footprint. In addition to a 2% output setpoint 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 over current, output short-circuit and over temperature protection insure safe operations under abnormal operating conditions.
The XRP7657 is offered in a RoHS compliant, “green”/halogen free 8-pin SOIC package.
