24.0 PROGRAMMABLE SWITCH
MODE CONTROL (PSMC)
The Programmable Switch Mode Controller (PSMC) is
a high-performance Pulse Width Modulator (PWM) that
can be configured to operate in one of several modes
to support single or multiple phase applications.
A simplified block diagram indicating the relationship
between inputs, outputs, and controls is shown in
Figure 24-1.
This section begins with the fundamental aspects of the
PSMC operation. A more detailed description of
operation for each mode is located later in
Section 24.3 “Modes of Operation”
Modes of operation include:
• Single-phase
• Complementary Single-phase
•Push-Pull
• Push-Pull 4-Bridge
• Complementary Push-Pull 4-Bridge
• Pulse Skipping
• Variable Frequency Fixed Duty Cycle
• Complementary Variable Frequency Fixed Duty
Cycle
• ECCP Compatible modes
- Full-Bridge
- Full-Bridge Reverse
• 3-Phase 6-Step PWM
