    XRP7720
    Quad Output Universal Customizable PMIC with PFM
    January 2014 Rev. 1.0.0 GENERAL DESCRIPTION
    The XRP7720 is a quad output universal customizable PMIC comprised of a quad channel Digital Pulse Width Modulated (DPWM) Step down (buck) controller and 5V LDO. A wide 4.75V to 5.5V and 5.5V to 18V input voltage dual range allows for single supply operation from standard power rails. It is pin compatible to the popular XRP7724 and provides full flexibility during the development phase while offering a cost effective option for high volume production units. With integrated FET gate drivers, it can operate from 105kHz to 1.23MHz with independent channel-to-channel programmable operating frequency, the XRP7720 reduces overall component count and solution footprint while optimizing conversion efficiencies. A selectable digital Pulse Frequency Mode (DPFM) and low operating current result in better than 80% efficiency down to 10mA load provides support for portable and Energy Star compliant applications. Each XRP7720 output channel is individually programmable down to a minimum 0.6V with a resolution of 2.5mV, and configurable for precise soft start and soft stop sequencing, including delay and ramp control. During development, the XRP7720ILB-DEV is configured using PowerArchitectTM 5.1 (PA 5.1) through an I2C interface, allowing for short development of the power system and short time to market for the entire system. Once development is completed and volume production is ready to commence, Exar will assign a unique part suffix and deliver a customized XRP7720. Built-in independent output over voltage, over temperature, over-current and under voltage lockout protections ensure safe operation under abnormal operating conditions. The XRP7720 is offered in a RoHS compliant, "green"/halogen free 44-pin TQFN package. FEATURES Pin Compatible to XRP7724 SMBus Compliant I2C Interface available on XRP7720ILB-DEV Only Supported by PowerArchitectTM 5.1 XRP7720ILB-DEV Only Quad Channel Step-down Controller Digital PWM 105kHz-1.23MHz Operation Individual Channel Frequency Selection Patented digital PFM with Ultrasonic Mode Integrated MOSFET Drivers Programmable 5 coefficient PID control 4.75V to 18V Input Voltage 4.75V-5.5 and 5.5V-18V Input Range 0.6V to 5.5V Output voltage 3 x 15V Capable PSIOs + 2 x GPIOs Full Start/Stop Sequencing Support Built-in Thermal, Over-Current, UVLO and Output Over-Voltage Protections On Board 5V Standby LDO 7x7mm TQFN44 Package APPLICATIONS Blade Servers Micro Servers Network Adapter Cards Switches/Routers Video Surveillance Systems Exar Corp ...
