Not Recommended for New Designs XRP7725 (Suggested Alternate: XRP7714) XRP7725 Intel Node Manager Compatible Programmable Intel Node Manager Compatible Programmable Power Management System Power Management System February 2019 Rev. 1.0.2 GENERAL DESCRIPTION FEATURES Quad Channel Step-down Controller The XRP7725 is a quad channel Digital Pulse Width Modulated (DPWM) Step down (buck) Digital PWM 105kHz-1.23MHz Operation controller. A wide 4.75V to 5.5V and 5.5V to Individual Channel Frequency Selection 25V input voltage dual range allows for single Patented digital PFM with Ultrasonic mode supply operation from standard power rails. Patented Over Sampling Feedback With integrated FET gate drivers, two LDOs for Instantaneous current monitoring standby power and a 105kHz to 1.23MHz Intel Node Manager Compatible independent channel to channel programmable 4.75V to 25V Input Voltage constant operating frequency, the XRP7725 reduces overall component count and solution 4.75V to 5.5V and 5.5V to 25V Input Ranges footprint and optimizes conversion efficiencies. A selectable digital Pulse Frequency Mode 0.6V to 5.5V Output Voltage (DPFM) and low operating current result in 2 SMBus Compliant - I C Interface better than 80% efficiency down to 10mA load Full Power Monitoring and Reporting provides support for portable and Energy Star compliant applications. Each XRP7725 output 3 x 15V Capable PSIO + 2 x GPIOs channel is individually programmable down to Full Start/Stop Sequencing Support a minimum 0.6V with a resolution of 2.5mV, Built-in Thermal, Over-Current, UVLO and configurable for precise soft start and soft and Output Over-Voltage Protections stop sequencing, including delay and ramp On Board 5V and 3.3V Standby LDOs control. On Board Non-volatile Memory The XRP7725 operation is fully controlled via 2 Supported by PowerArchitect Design an SMBus-compliant I C interface allowing for Tool Version 5 (PA5) advanced local and/or remote reconfiguration, full performance monitoring and reporting as well as fault handling. APPLICATIONS Built-in independent output over voltage, over Blade Servers temperature, over-current and under voltage Micro Servers lockout protections insure safe operation Network Adapter Cards under abnormal operating conditions. Base Stations Switches/Routers The XRP7725 is offered in a RoHS compliant, Broadcast Equipment green/halogen free 44-pin TQFN package.
