GENERAL DESCRIPTION
The SP7662 is a synchronous voltage mode
PWM step down (buck) regulator capable of a
constant output current up to 12 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.
With a 300kHz constant operating frequency
and integrated high and low side switch, the
SP7662 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.
Built-in current limiting, UVLO, output short-
circuit and over temperature protection insure
safe operation under abnormal operating
conditions.
The SP7662 is offered in a RoHS compliant,
lead free 26-pin 7mmx4mm DFN package.
