GENERAL DESCRIPTION
The XRP7725 is a quad channel Digital Pulse
Width Modulated (DPWM) Step down (buck)
controller. A wide 4.75V to 5.5V and 5.5V to
25V input voltage dual range allows for single
supply operation from standard power rails.
With integrated FET gate drivers, two LDOs for
standby power and a 105kHz to 1.23MHz
independent channel to channel programmable
constant operating frequency, the XRP7725
reduces overall component count and solution
footprint and optimizes conversion efficiencies.
A selectable digital Pulse Frequency Mode
(DPFM) and low operating current result in
better than 80% efficiency down to 10mA load
provides support for portable and Energy Star
compliant applications. Each XRP7725 output
channel is individually programmable down to
a minimum 0.6V with a resolution of 2.5mV,
and configurable for precise soft start and soft
stop sequencing, including delay and ramp
control.
The XRP7725 operation is fully controlled via
an SMBus-compliant I
2
C interface allowing for
advanced local and/or remote reconfiguration,
full performance monitoring and reporting as
well as fault handling.
Built-in independent output over voltage, over
temperature, over-current and under voltage
lockout protections insure safe operation
under abnormal operating conditions.
The XRP7725 is offered in a RoHS compliant,
“green”/halogen free 44-pin TQFN package.
