Microchip Technology PIC16(L)F1769 8-Bit Microcontrollers
Microchip Technology PIC16(L)F1769 8-Bit Microcontrollers combine intelligent analog integration with digital peripherals to suit a variety of functions and applications. These low-pin count MCUs 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. The PIC16(L)F1769 MCUs also include a Programmable Ramp Generator (PRG) peripheral that eliminates the CPU burden related to slope and ramp compensation in power conversion applications, improving frequency stability and system efficiency.
The PIC16(L)F1769 MCUs enable 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 Microchip Technology PIC16(L)F1769 MCUs are offered in compact SSOP-20, SOIC-20, PDIP-20, and QFN-20 packages for design flexibility.
