High Performance Digital Control
Devices in the PIC18F, PIC24 and dsPIC33F families offer
8-bit and 16-bit solutions for fast calculation of digital control
loops. In addition, these families have device variants with
fast ADC peripherals and specialized PWM modules that are
optimized for power control applications.
A selection of devices for digital power control is shown in
the table below. There are many other Microchip devices that
could be used, but these devices represent low-cost and
small package choices.
Devices in the PIC18F family have an 8-bit CPU with a
hardware multiplier. The PIC18 is a good choice for moderate
control loop rates (1-10 KHz). Devices in the dsPIC33F family
have a 16-bit CPU with DSP resources. This family is a good
choice if you need to execute multiple control loops at a
faster rate. Devices in the PIC24 family offer an intermediate
solution with 16-bit calculation performance.

Drive 1
The dsPIC33FJ06GS202 device has a Power Supply PWM
module that can generate high switching frequencies with
very fine edge resolution. This PWM module can also
generate phase shifted PWM signals for advanced power
supply applications.
The 28-pin dsPIC33FJ06GS202 device can provide a highly
integrated solution for LED lighting applications. The PWM
peripheral can drive 3 strings of LEDs, replacing 3 separate
analog control ICs. Furthermore, there are resources left
over for active power factor correction (PFC) and digital
communications.
