XRP9710 and XRP9711
Dual 6A Programmable Power Module
January 2014
GENERAL DESCRIPTION
The XRP9710 and XRP9711 are programmable
step down power modules providing two 6A
outputs. The module package contains the
switching controller, power MOSFETs,
inductors and support components. As a
result, external components are minimal. A
wide input voltage range (4.75V to 5.5V or
5.5V to 22V) allows for single supply operation
from standard power rails.
The modules measure only 12x12x2.75mm
making it half the size of competing 12V
capable 6Amp modules. The 2.75mm height
allows them to be placed on the back of
boards or under heat sinks where other
solutions cannot, yet they contain two full 6A
buck power stages and two Digital Pulse Width
Modulator (DPWM) controllers with gate
drivers. Designed to operate at a constant
PWM switching frequency between 500kHz and
750kHz, the Digital Pulse Frequency Mode
(DPFM) results in better than 80% efficiency
at light load currents and low operating
current allow for portable and Energy Star
compliant applications. Each XRP9710 or
XRP9711 output can be individually
programmed to as low as 0.6V with a
resolution as fine as 2.5mV, and configurable
for precise soft start and soft stop sequencing,
including delay and ramp control.
The XRP9710/1 is fully controlled via a SMBus-
compliant I²C interface allowing for advanced
local and/or remote reconfiguration, full
performance monitoring and reporting as well
as fault handling.
Built-in output over-voltage, over-
temperature, over-current and under voltage
lockout protections insure safe operation
under abnormal operating conditions.
The XRP9710/1 is offered in a RoHS
compliant, halogen-free LGA package.
