GENERAL DESCRIPTION
The SP7652 is a synchronous voltage mode
PWM step down (buck) regulator capable of a
constant output current up to 6Amps. A wide
2.5V to 28V power input voltage range, with
the required 5V biasing voltage, allows
conversions from industry standard 5V, 12V,
18V and 24V power rails.
With a 600kHz constant operating frequency
and integrated high and low side switch, the
SP7652 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 Under voltage lockout (VLO) on both
V CC and V IN , outputs short-circuit and over
temperature protection insure safe operation
under abnormal operating conditions.
The SP7652 is offered in a RoHS compliant,
lead free 26-pin 7mmx4mm DFN package.
