XRP7714  
Quad Channel Digital PWM Step Down Controller  
September 2010  
Rev. 1.1.4  
GENERAL DESCRIPTION  
APPLICATIONS  
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 I2C 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.  
Multi Channel Power Supplies  
Audio-Video Equipments  
Industrial & Telecom Equipments  
Processors & DSPs Based Equipments  
FEATURES  
4 x 5A Channel Step Down Controller  
Programmable Output Voltage 0.9V-5.1V  
Programmable 1.5MHz DPWM Frequency  
Integrated FET Drivers  
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  
4.75V to 5.5V and 5.5V to 25V Input  
Voltage Range  
Up to 6 Reconfigurable GPIO Pins  
Fully Programmable via I2C Interface  
Independent Digital Pulse Width  
Modulator (DPWM) channels  
25V.  
An I2C bus interface is provided to  
Complete Monitoring and Reporting  
Complete Power Up/Down Sequencing  
program the IC as well as to communicate  
with the host for fault reporting and handling,  
power rail parameters monitoring, etc.  
Full On Board Protection  
OTP, UVLO, OCP and OVP  
The device offers a complete solution including  
independently programmable: soft-start, soft-  
stop, start-up delay and ramp of each PWM  
regulator.
