MCP1631VHVT-330E/SS

高速脉宽调制器 High-Speed, Pulse Width Modulator

General Description

The MCP1631/MCP1631V is a high-speed analog pulse width modulator PWM used to develop intelligent power systems.  When combined with a microcontroller, the MCP1631/MCP1631V will control the power system duty cycle providing output voltage or current regulation. The microcontroller can be used to adjust output voltage or current, switching frequency and maximum duty cycle while providing additional features making the power system more intelligent, robust and adaptable.
