Exar's Newest Programmable Power Management System: XRP7724
Quad Channel Digital PWM/PFM Programmable Power Management System
The XRP7724 is Exar's next generation programmable power management system.  The system is a single input, quad output, step down switching regulator controller with integrated gate drivers and dual LDO output all fully programmable via an I2C based SMBus compliant serial interface.  The sytem offers a wide input voltage range (4.75V to 25V), and ouput range (0.6V to 5.5V) with switching conversion frequencies programmable from 106kHz to 1.2MHz in digital PWM and PFM modes.  An additional five GPIOs for system control complete the solution all packed into a 7mmx7mm TQFN package.  
Exar's PowerArchitectTM 5.0 software design tool enables designers to intelligently configure the power supply's voltage setting and current thresholds, fault monitoring and response, soft start and active shutdown timing, channel sequencing, phase shift management and loop response amongst other features.
