Exar XRP7714 Series Quad Channel
Digital PWM Step Down Controller

Exar's XRP7714 is a Quad Channel Digital Pulse-Width Modulated (PWM) Step-Down Controller with a built-in LDO for standby power and GPIOs. The XRP7714 provides a complete power management solution in one IC and is fully programmable via an I2C serial interface. Independent Digital Pulse Width Modulator (DPWM) channels of the Exar XRP7714 Quad Channel Digital PWM Step Down Controller regulates output voltages and provides all of the required protection functions such as current limiting and over-voltage protection. This Exar XRP7714 series of Quad Channel Digital PWM Step Down Controller offers a complete solution including independently programmable: soft-start, soft-stop, start-up delay and ramp of each PWM regulator.
