MaxLinear SP7663

Description

The SP7663 is a synchronous voltage mode PWM step down (buck) regulator capable of a constant output current up to 6 Amps. A wide 5V to 22V single input voltage range allows for single supply operations from industrystandard 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 setpoint accuracy, this device provideshigh 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 shortcircuit and over temperature protection insure safe operation under abnormal operatingconditions.The SP7663 is offered in a RoHS compliant, lead free 26-pin 7mmx4mm DFN package.
