EXAR XRP7713EVB-DEMO-1-KIT 评估板, 降压直流/直流控制器, 3路
The XRP7713EVB is an evaluation board for XRP7713, a three output pulse width modulated PWM step down DC to 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 from 300KHz to 1.5MHz enables the user to optimize between efficiency and component size. An I2C bus interface is provided to program the IC as well as to communicate with the host for fault reporting and handling, power rail parameters monitoring, etc.
