FAQ

1. What does the “-50” in the part number mean, and how does it differ from standard versions?
   
   • -50 indicates operation at 50 MIPS, providing 25% more CPU bandwidth than the common 40 MIPS variants.
   • Higher MIPS enables more complex digital compensators, additional digital filters, or concurrent communication stacks within the same control loop period, enhancing dynamic response.
2. What do the “-I/PT” suffixes specifically mean?
   
   • -I: Industrial temperature range (-40°C to +85°C).
   • /PT: 64-lead TQFP package, 10mm×10mm body, 0.5mm pin pitch.
3. What are the practical benefits of 50 MIPS for digital power designs?
   
   • Completes digital PID/2P2Z compensator calculations in shorter control periods, supporting higher switching frequencies.
   • Spare CPU time can handle PMBus communication, fault diagnosis, soft-start management, and online parameter tuning, making the power system more intelligent.
4. Which power topologies does this DSC support?
   
   • Four complementary PWM pairs with programmable dead-time and independent phase shift suit half-bridge, full-bridge, active-clamp forward, LLC resonant, and synchronous rectification topologies.
   • Working with high-speed comparators and ADC, it flexibly implements peak current mode control and valley switching.
5. How do the ADC and PWM work together for cycle-by-cycle current limiting?
   
   • Four high-speed analog comparators directly compare current-sense signals with a threshold; their outputs can directly shut down PWM without CPU intervention, achieving hardware over-current protection in tens of nanoseconds.
   • Simultaneously, the 10-bit 4 Msps ADC can be triggered synchronously with PWM to precisely sample current and voltage at specific instants for digital average-current control or protection.
6. How many communication interfaces does it have? Can it act as a PMBus or I2C master?
   
   • It features two I2C modules (supporting master/slave), ideal for implementing PMBus or SMBus communication with external power management ICs or a host supervisory system.
   • Additional 2× UARTs and 2× SPIs can simultaneously serve debug, fieldbus, or other peripheral connections.
7. What tools are needed to develop and debug with this chip?
   
   • Free MPLAB X IDE and XC16 compiler from Microchip.
   • Hardware debugging via PICkit 4 or MPLAB ICD 4, supporting in-circuit programming and real-time debugging.
   • MPLAB Code Configurator (MCC) quickly generates peripheral drivers; the Digital Power Compensator Design Tool aids in calculating loop parameters.
8. Is the built-in 10-bit ADC accurate enough for high-precision power supplies?
   
   • 10-bit resolution paired with 4 Msps high-speed sampling adequately handles voltage/current monitoring and protection in most switching power supplies.
   • Oversampling and digital filtering via the DSP engine can improve effective resolution for higher precision requirements.
9. What switching frequencies can the PWM generate?
   
   • The PWM clock (via PLL) can reach GHz range, generating switching frequencies from tens of kHz to over 1 MHz while maintaining fine duty-cycle resolution.
   • Actual resolution depends on the chosen PWM clock and switching frequency; better than 10-bit duty-cycle resolution is typical at 100 kHz.
10. Does this chip require an external clock or reset circuitry?
    
    • It has a built-in high-accuracy on-chip oscillator and PLL, capable of stable operation without an external crystal, saving PCB space and BOM cost.
    • Integrated Power-on Reset (POR) and Brown-out Reset (BOR) ensure reliable start-up without an external reset IC.
