6 GENERAL DESCRIPTION The XRP7714 is a quad-output pulse-width modulated (PWM) step-down DC-DC controller with a built-in LDO for standby power and GPIOs.
The device 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 regulate output voltages and provide all required protection functions such as current limiting and over-voltage protection.
Each output voltage can be programmed from 0.
9V to 5.
1V without the need of an external voltage divider.
The wide range of the programmable DPWM switching frequency...
