MCUs ideal for power conversion

18 March 2015 DSP, Micros & Memory

The 8-bit PIC16(L)F1769 microcontroller (MCU) family is Microchip’s first to offer up to two independent closed-loop channels. This is achieved with the addition of a programmable ramp generator (PRG), which automates slope and ramp compensation and increases stability and efficiency in hybrid power conversion applications. The PRG provides real-time (down to the nanosecond) responses to a system change without CPU interaction for multiple independent power channels. The addition of hardware-based LED dimming control makes this viable as an LED dimming engine synchronising switching control and eliminating LED current overshoot and decay.
