PIC16HV785 Boost LED Driver Application
PIC16HV785 Flyback Converter with PFC and Dimming Control
Mixed-Signal LED Drivers
Some devices, such as the PIC16F616, have a SR latch
module that can be used in many different ways along with
the comparators and other digital signal events. Events such
as clock pulses or comparator signals can be programmed to
set or reset the SR latch. These programming options allow
almost any kind of control signal to be generated.
The PIC16F785 has two on-chip op amps, two on-chip
comparators, two SR latch PWM modules and an adjustable
voltage reference. This combination of peripherals can be
digitally configured to implement a wide variety of SMPS
circuit topologies.
