Universal PMIC 40V Quad Output Digital PWM/PFM Demo Board

Overview

TopologyBuck Converter
Input voltage6-40 V
Output 13.3 V / 5 A
IC revision1.0.0

Description

The XR77129EVB-DEMO-1 board is a complete four channel power system. It is configured to provide 5.0V, 12V, 3.3V and 2.5V at a maximum of 5A, 3A, 5A and 10A loads respectively. The 2.5V supply can be adjusted in 5mV increments. The 3.3V and 5V supplies are adjustable in 10mV increments. The 12V output is using external resistor divider. The order and ramp rates for each supply can be programmed to accommodate any sequencing requirement. All power supply operations can be controlled over an I2C interface. Faults, output voltages and currents can also be monitored. Two GPIO and three PSIO signals are available and can be programmed to provide a variety of functions. Unused GPIO/PSIO pins can be programmed as I/O expansion for a microcontroller. The board is supported by PowerArchitectTM 5.2 or later and plugs directly onto the interposer board acting as an interface to an Arduino controller or Exar’s XCM.
