SP7663

SP7663 PowerbloxTM 6A 600KHz Synchronous Step Down Regulator August 2012 Rev. 2.2.0 GENERAL DESCRIPTION APPLICATIONS 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 industry standard 5V, 12V and 18V power rails. Operations down to 3V are supported with an additional biasing voltage.  Distributed Power Architectures  Point of Load Converters  Power Supply Modules  FPGAs, DSPs and Processors Supplies FEATURES 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 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.  6A Continuous Cu...
