8 Intelligent Power Supply Design Solutions
Microchip makes many families of 8-, 16- and 32-bit
MCU and 16-bit DSC solutions that can be used in
various intelligent power applications, enabling a
designer to support the level of digital integration and
performance required for the application.
PIC10F Microcontroller Product Family
The 6-pin PIC10F family allows digital features to be
integrated into any power supply design with a cost
structure that makes them nearly disposable. The
on-chip ADC, comparator and timer peripherals can
be used to augment analog power supply designs,
providing On/Off control, soft-start, power sequencing
or monitoring features to the application. Only simple
programming skills are required to create the software.
The PIC10F features include:
■
2x3 DFN or 6-pin SOT-23 package
■
Internal oscillator
■
Comparator
■
Internal 8-bit ADC
PIC12F and PIC16F Microcontroller
Product Families
The PIC12F devices are available in small 8-pin
packages, while PIC16F variants are offered in 14-pin
through 64-pin packages. These device families are
suitable for proportion control (Level 2 integration).
Some variants in the PIC16F family have one or more
enhanced capture compare PWM (ECCP) modules
that can be used to generate references for analog
control loops. Built-in ADCs can be used to monitor
input/output voltage and current and temperature.
Comparators can be employed to monitor fault inputs.
Communication peripherals like UART, SPI and I

can be used for remote monitoring and control. Key
features of these microcontroller families are:
■
Up to 5 MIPS of operation
■
One or more ECCP modules
■
Comparator with input multiplexer
■
8-bit or 10-bit ADC
■
Internal RC Oscillator
■
Internal 5V Shunt Regulator
■
Communication interfaces: USART, SPI, I

PIC18F Microcontroller Product Family
The PIC18F product family also has an 8-bit CPU
and offers extended performance over the PIC16F
device family. The PIC18F device family can operate at
speeds up to 16 MIPS and has a hardware multiplier
for faster calculation of control algorithms. There are
variants in the PIC18F family with specialized PWM,
ECCP modules. The PIC18F family devices are good
matches for confi guration or topology control (Level 3).
An internal 10- or 12-bit ADC with fast sampling rate
can be used to monitor feedback parameters and can
monitor in/out voltage and currents. Communication
peripherals like UART, SPI and I

C can be used to
implement remote monitoring and controlling features.
