• Development Board Introduction:

  As a Rising Star, Cortex-m-Core Digital Power Supply Relies on Simple Development Process (Keil) and Powerful Floating-Point Arithmetic Capability (FPU,DSP),.

High-Precision Timer (Hrtim, 216 Picoses), Dynamic Cache (Ccmram), Direct Memory Access (DMA), High-Speed ADCs (5 MSPs)

and Other Advantages, Playing an Increasingly Important Role in the Field of Digital Power Supply, the Launch of Buck and Buck-Boost Two Development Boards,

Let You Quickly Get Familiar with and Master the Basic Control Principle of Digital Power Supply and Digital Loop Compensation Design (2 P2z, 3 P3z, PID).
