GENERAL DESCRIPTION
   The XRP7708 and XRP7740 are quad-output pulse-width modulated (PWM) step-down DCDC controllers with a built-in LDO for standby power and GPIOs. The devices provide a complete power management solution in one IC and are fully programmable via an I2C serial interface. Independent Digital Pulse Width Modulator (DPWM) channels regulate output voltages and provide all required protection functions such as current limiting and over-voltage protection.
