Power Supply Design Integration Levels
Level 1 Integration: On/Off Control
At Level 1, electronic intelligence augments a
standard analog design. The intelligence provides
limited On/Off control functions such as start-up
sequencing, automatic shutdown and watchdog fault
detection functions. More sophisticated solutions
can provide logging functions for later failure
analysis, remote communication and customized
thermal control algorithms. With Level 1 intelligence,
a designer can ensure that the power supply has
a deterministic response to system fault events.
Solutions at this level benefit from Microchip’s
Baseline and Mid-Range MCUs and analog products.
Now it’s easy to make your existing analog
power supply intelligent without major hardware
modifications and few software changes.
Microchip’s PIC10F and PIC12F 8-bit low pin count
and small package microcontrollers with built-in
peripherals, such as ADC, PWM and GPIOs, can
make the existing analog power supplies intelligent
by controlling the output sequencing and monitoring
of input/output voltage, current and temperature.
Level 2 Integration: Proportional Control
This integration level adds additional digital control to the standard analog design. In addition to Level 1 control
features, it is possible to control output voltage, voltage limits, current limits and thermal limits. At this level, most
of the operating parameters of the analog power supply can be digitally controlled and monitored. Different

events or faults. A PWM peripheral provides direct control of the analog PWM circuitry of the power unit. The PWM
control can be used to gate the analog power supply under power-up conditions to provide soft-start. The MCU
can monitor the power supply input current during the soft-start to ensure that components are not over-stressed.
Serial communication peripherals allow coordination from a host device, control and monitoring of cooling fans, and
monitoring of temperature sensors.

can be fine-tuned to provide
coordination between multiple
power supplies in a system.
Depending on the system I/O
requirements, 8-bit solutions in
the PIC12, PIC16 or PIC18 device
families can provide the ideal
solution. In larger systems, the
16-bit PIC24 device family can
provide more communication
peripherals.
A Level 2 control system has much
greater integration with the power
supply and allows greater power
supply environment monitoring. An
ADC is used to monitor the power
supply inputs and outputs. On-chip
comparators can also be employed
to ensure fast response to system
soft-start profiles and current limits
can be programmed to suit the
application. The output voltage
