开关控制器 4Ch Digital Pwr Cntr w/LDO prog. thru PC Quad Channel Digital PWM Step Down Controller

GENERAL DESCRIPTION  

The XRP7714ILB-F 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.
