MCP1631HV Digitally Controlled Programmable Current Source Reference Design
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...
