Microchip's MCP1630 boost mode LED driver demo board is a step-up, switch-mode DC/DC converter used for power LED applications. The demo board provides a 350 mA or 700 mA constant current source with a jumper selection. The input operating voltage range is 9 VDC to 16 VDC, and the board can supply up to 30 W to a string of power LEDs. The MCP1630 is designed for use with an MCU that provides a reference clock source. The MCU controls the PWM frequency and maximum duty cycle. The switching frequency can be up to 1 MHz, depending on the application requirements. The MCU can also control the reference input for the error amplifier when dimming or soft start functions are required. Multiple MCP1630 devices can be attached to an MCU to support multiple power channels.
