XRP7665
3A 18V Synchronous Step-Down Converter
March 2013
GENERAL DESCRIPTION
The XRP7665 is a synchronous current-mode
PWM step down (buck) regulator capable of a
constant output current up to 3 Amps. A wide
4.50V to 18V input voltage range allows for
single supply operations from industry
standard 5V and 12V power rails.
With a 340kHz constant operating frequency
and integrated high and low side
100mΩ/90mΩ MOSFETs, the XRP7665 reduces
the overall component count and solution
footprint. Current-mode control provides fast
transient response and cycle-by-cycle current
limit. An adjustable soft-start prevents inrush
current at turn-on, and in shutdown mode the
supply current drops to 0.1µA.
Built-in output over voltage (open load), over
temperature, cycle-by-cycle over current and
under voltage lockout (UVLO) protections
insure safe operations under abnormal
operating conditions.
The XRP7665 is a pin and function compatible
device to MP1484 and a 3A pin to pin upgrade
to XRP7664.
The XRP7665 is offered in a RoHS compliant,
“green”/halogen free 8-pin exposed pad SOIC
package.
