Not Recommended for New Designs XRP7724 (Suggested Alternate: XRP7714) Quad Channel Digital PWM/PFM Programmable Power Management System February 2019 Rev. 1.0.2 GENERAL DESCRIPTION APPLICATIONS Servers The XRP7724 is a quad channel Digital Pulse Base Stations Width Modulated (DPWM) Step down (buck) Switches/Routers controller. A wide 4.75V to 5.5V and 5.5V to Broadcast Equipment 25V input voltage dual range allows for single Industrial Control Systems supply operation from standard power rails. Automatic Test Equipment With integrated FET gate drivers, two LDOs for Video Surveillance Systems standby power and a 105kHz to 1.23MHz FEATURES independent channel to channel programmable constant operating frequency, the XRP7724 Quad Channel Step-down Controller reduces overall component count and solution Digital PWM 105kHz-1.23MHz Operations footprint and optimizes conversion efficiencies. Individual Channel Frequency Selection A selectable digital Pulse Frequency Mode Patented digital PFM with Ultrasonic mode (DPFM) capable of better than 80% efficiency at light current load and low operating current Patented Over Sampling Feedback allow for portable and Energy Star compliant Integrated MOSFET Drivers applications. Each XRP7724 output channel is Programmable 5 coefficient PID control individually programmable as low as 0.6V with a resolution as fine as 2.5mV, and configurable 4.75V to 25V Input Voltage for precise soft start and soft stop sequencing, 4.75V-5.5V and 5.5V-25V Input Ranges including delay and ramp control. 0.6V to 5.5V Output voltage The XRP7724 operations are fully controlled via 2 SMBus Compliant - I C Interface 2 a SMBus-compliant I C interface allowing for Full Power Monitoring and Reporting advanced local and/or remote reconfiguration, full performance monitoring and reporting as 3 x 15V Capable PSIO + 2 x GPIOs well as fault handling. Full Start/Stop Sequencing Support Built-in independent output over voltage, over Built-in Thermal, Over-Current, UVLO temperature, over-current and under voltage and Output Over-Voltage Protections lockout protections insure safe operation under On Board 5V and 3.3V Standby LDOs abnormal operating conditions. On Board Non-volatile Memory The XRP7724 is offered in a RoHS compliant, green/halogen free 44-pin TQFN package.
