Description

Multiple Independent Closed-Loop Power Conversion Channels The PIC16F1779 product family is purpose-built to support the demands of highly integrated, power-conversion applications. These devices offer multiple independent closed-loop power channels and system management capabilities, while providing an 8-bit platform that simplifies design and helps eliminate many discrete components in power-conversion systems. In addition, the Programmable Ramp Generator (PRG) works to stabilize power output, improving frequency stability and system efficiency. The family includes four devices, available in pin counts ranging from 14 to 40 pins and program memory sizes up to 28KB. LED Dimming Engine The PIC16F1779 family offers a unique hardware-based LED dimming control function enabled by the interconnection of the Data Signal Modulator (DSM), on-chip op amp and 16-bit PWM. The combination of these peripherals creates an LED dimming engine that synchronizes switching control; thus eliminating LED current overshoot and decay. This synchronization of the output switching helps smooth visible dimming, minimizes color shift, increases LED life and reduces heat. High Integration of Intelligent Analog and Digital Features The devices integrate up to four complete sets of Core Independent Peripherals (CIPs), designed to optimally drive switch mode power supplies and apply sophisticated output modulation for high-resolution, dimmable solid-state lighting applications. The family also offers Intelligent Analog peripherals, including op amps, 10-bit Digital-to-Analog Converter (DAC), high-speed comparators, zero cross detect and two 100mA high-current I/Os.
