MCP1631HV Digitally Controlled Programmable Current Source Reference Design (MCP1631RD-DCPC1)

The MCP1631HV Digitally Controlled Programmable Current Source Reference Design is used to drive and dim one or more power LEDs in a series or parallel topology (depending on the LED’s capability). The reference design may also be used to charge one to four cell NiMH/NiCd or one to two cell Li-Ion battery packs. The board uses the MCP1631HV high-speed analog PWM controller and PIC16F616 microcontroller to generate the proper dimming ratio for LEDs or charge algorithm for NiMH, NiCd and Li-Ion batteries. The boards is used to evaluate Microchip’s MCP1631HV in a SEPIC power converter application.

Возможности

    • Input Operating Voltage Range: +3.5V to +16V
    • Firmware default output current of 700 mA with dimming ratio 10:1 (70 mA/step)
    • Maximum output current of 1000 mA
    • Maximum output power of 8.5W
    • Drive one or more LEDs
    • Firmware for charging Li-Ion, NiMH, and NiCd batteries
    • Single ON/OFF/Dimming switch
    • Status and fault indication
    • Hardware and software overvoltage protection (OVP) set to 9.0V. The software value can be modified in the source code to be less than 9.0V
