Microchip – MCP19116/7: Digitally Enhanced Power Analog Controllers

Microchip-logo     NextArticle
The MCP19116/7 devices are highly integrated, mixed- signal low side synchronous controllers that operate from +4.5V to +42V. The family features an analog PWM controller with an integrated microcontroller core used for LED lighting systems, battery chargers and other low side switch PWM applications. Complete customization of device operating parameters, start-up or shutdown profiles, protection levels and fault handling procedures are accomplished by setting digital registers using Microchip’s MPLAB® X Integrated Development Environment software and one of Microchip’s many in-circuit debugger and device programmers.
