GENERAL DESCRIPTION
The XRP7714 is a quad-output pulse-width
modulated (PWM) step-down DC-DC controller
with a built-in LDO for standby power and
GPIOs. The device provides a complete power
management solution in one IC and is fully
programmable via an I
2
C serial interface.
Independent Digital Pulse Width Modulator
(DPWM) channels regulate output voltages
and provide all required protection functions
such as current limiting and over-voltage
protection.
Each output voltage can be programmed from
0.9V to 5.1V without the need of an external
voltage divider. The wide range of the
programmable DPWM switching frequency
(from 300 KHz to 1.5 MHz) enables the user to
optimize between efficiency and component
size. Input voltage range is from 4.75V to
25V. An I
2
C bus interface is provided to
program the IC as well as to communicate
with the host for fault reporting and handling,
power rail parameters monitoring, etc.
The device offers a complete solution including
independently programmable: soft-start, soft-
stop, start-up delay and ramp of each PWM
regulator.
