Full Digital Power

A high-performance DSP engine and specialized peripherals are essential when you are implementing advanced software digital control loops for power applications. dsPIC DSCs feature a high-performance CPU and rich peripherals to create advanced power conversion designs with minimal requirements for external circuitry. The DSP engine performs single-cycle MAC with up to 40 bits of resolution, data saturation, zero overhead looping and barrel shifting to support fast control loop execution. Peripherals, such as high-speed PWM generators, ADCs, Programmable Gain Amplifiers (PGAs) and high-speed analog comparators can be tied together using an internal configurable control fabric so they can interact directly with one another, resulting in stunning performance gains in digital power applications.

dsPIC33A DSCs

• Our high-performance dsPIC33A Digital Signal Controllers (DSCs) with a 32-bit CPU offer up to 200 MHz performance and a Double Precision Floating-Point Unit (DP-FPU) coprocessor. These DSCs:
  • Accelerate computation in control loop execution
  • Enable model-based design

dsPIC33C DSCs

• Our single- and dual-core dsPIC33C family DSCs operate at up to 100 MHz/core and feature advanced on-chip peripherals for designing applications that target high-performance, intelligent power supplies
• These DSCs help you design different functions separately and integrate seamlessly using the main and secondary cores:
  • With the secondary core, you can execute latency-critical compensator algorithms
  • With the main core, you can run communication stack, safety and system-level functions

• Peripherals of dsPIC33 DSCs help reduce the Bill of Materials (BoM) and system costs by achieving various functions:
  • Simultaneous sampling using high-speed 12-bit, 3.5 Msps ADCs (dsPIC33C) and up to 40 Msps ADCs (dsPIC33A)
  • Signal conditioning using integrated PGAs/op amps
  • Robust communication using UART, SPI, I²C, PMBus^® and CAN/CAN FD interfaces
  • Waveform generation using analog comparators, with response time down to 5 ns, and 12-bit DACs

• Achieve numerous power topologies using configurable PWM control inputs with duty cycle down to 250 ps
• Design with form factor as small as 4 × 4 mm and achieve IPC-9592B qualification
• Real-time firmware upgrade of power supplies used in servers
• Develop safety-critical applications that meet the ISO 26262, IEC 61508 and IEC 60730 standards for automotive, industrial and household appliances using safety manuals, FMEDA reports, diagnostic software and TÜV SÜD-certified MPLAB^® XC compiler
