PIC16F176X / 7X Microcontrollers

The PIC16F177x / 176x product families from Microchip Technology are purpose-built to support the demands of highly integrated, low-wattage 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. This family includes the programmable ramp generator (PRG) peripheral which eliminates the CPU burden related to slope and ramp compensation in power-conversion applications, improving frequency stability and system efficiency.

The family enables the ability to interconnect the on-chip peripherals to create custom functions specific to each application. The combination of these peripherals creates an LED dimming engine that synchronizes switching control and faster turn-off, thus eliminating LED current overshoot and decay. This synchronization of the output switching helps smooth visible dimming, minimizes color shift, and reduces heat, which increases LED life. The family includes four devices available in pin counts ranging from fourteen to forty pins and program memory sizes up to 28 KB.
