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.

FEATURES
• Dynamically adjustable output current
• Analog peak-current-mode PWM control
• I2C communication interface
• Integrated synchronous low side MOSFET drivers
• Integrated temperatures sense diode
• Boost, SEPIC, Flyback, and Cuk Topologies
• Integrated 8-Bit PIC® microcontroller
• Fixed frequency or quasi-resonant mode operation
• 8 (MCP19116) or 12 (MCP19117) GPIO
• Integrated high voltage linear regulator, with external output
• Integrated 10-bit A/D converter
