Product details
Overview
MA330024 from Microchip Technology is a 100-pin Plug-In Module (PIM) designed to demonstrate the dsPIC33FJ64GS610 digital signal controller for Switch Mode Power Supply (SMPS) applications, featuring integrated PWM generators (PWM1H/L through PWM9H/L), analog comparators, and dedicated fault protection inputs (FLT1–FLT23). It interfaces with the Explorer 16 Development Board and PICtail™ Plus Daughter Board for rapid SMPS prototyping.
For engineers reviewing the MA330024 datasheet, MA330024 pinout, MA330024 application, or MA330024 equivalent, this module enables evaluation of high-precision voltage/current feedback control, multi-phase PWM timing synchronization, and real-time fault response in digitally controlled power converters.
Technical Context
The MA330024 implements a fixed 100-pin TQFP-to-PIM interface mapping that routes all dsPIC33FJ64GS610 peripheral signals-including eight independent PWM pairs, six analog comparators (CMP1A–CMP4D), and 24 configurable fault inputs (FLT1–FLT23)-to standardized PIM headers. Critical power control functions like VIN_Feedback (RB4), Current Sense 1/2 (RB0/RB3), and LOAD (RE4) are assigned to dedicated PIM pins for direct connection to external sensing circuitry.
It supports synchronous SMPS topologies via hardware-accelerated PWM phase alignment (SYNCI1–SYNCI4), real-time ADC sampling triggered by PWM events, and comparator-based fast fault shutdown (<100 ns response). The module exposes all 16-channel ADC inputs (AN0–AN23), four DAC outputs (DACOUT on RB9), and dual UART/I²C/SPI interfaces for system monitoring and configuration.

FAQ
What is the primary function of the MA330024 Plug-In Module?
The MA330024 Plug-In Module serves as a hardware interface platform that mounts the dsPIC33FJ64GS610 digital signal controller onto the Explorer 16 Development Board. It provides direct access to all critical SMPS control peripherals-including PWM outputs, analog feedback inputs, fault protection signals, and communication interfaces-enabling rapid prototyping and validation of digitally controlled power supplies without custom PCB design. MA330024 itself contains no active silicon; it is a precision-mapped interposer board.
Does the MA330024 include the dsPIC33FJ64GS610 microcontroller?
Yes, the MA330024 is a complete plug-in module that integrates the dsPIC33FJ64GS610 digital signal controller in a 100-pin TQFP package mounted on a rigid PCB with standardized 100-pin male headers. The device is pre-soldered and tested, and all I/O signals-including PWM, ADC, comparator, and fault inputs-are routed to clearly labeled test points and headers per DS70612A.
Can the MA330024 be used with development tools other than Explorer 16?
No-the MA330024 is mechanically and electrically designed exclusively for use with the Explorer 16 Development Board (DM240001) and PICtail™ Plus Daughter Boards. Its 100-pin male header layout matches the Explorer 16 socket footprint and pinout definition; attempting to use it with non-Microchip base boards will result in misalignment, incorrect signal mapping, or physical damage due to incompatible header spacing or keying.
Which power supply topologies are supported by the MA330024 evaluation platform?
The MA330024 supports evaluation of multiple switch-mode topologies including interleaved boost PFC, phase-shifted full-bridge, active clamp forward, synchronous buck/boost, and three-phase inverter configurations. This is enabled by its full complement of nine PWM pairs with independent dead-time control, six analog comparators for peak-current-mode control, and 23 fault inputs for cycle-by-cycle protection-features directly leveraged from the dsPIC33FJ64GS610's SMPS-optimized architecture.
Is firmware or software provided with the MA330024 module?
Yes, Microchip provides free firmware libraries and example projects for the MA330024, including SMPS reference designs for AC-DC and isolated DC-DC converters, available through MPLAB® X IDE and the dsPIC33F SMPS Software Library (DS50002731). These include fully documented source code for voltage/current loop control, PWM synchronization, fault handling, and communication protocols-compatible with the dsPIC33FJ64GS610 silicon on the MA330024 module.
