Microchip Technology MIC3202 HB LED Driver Evaluation Board

Microchip Technology MIC3202 HB LED Driver Evaluation Board is a hysteric, step-down, and constant-current driver for high-brightness LEDs. This Microchip Technology board offers a dedicated PWM input (DIM pin), enabling a wide range of pulsed dimming. The hysteretic control gives good supply rejection and fast response during the load transients and PWM dimming. The MIC3202 LED driver evaluation board features high-frequency switching operation of up to 1MHz, allowing the use of smaller external components that minimizes space and cost. This board is suited for interior or exterior lighting, architectural and ambient lighting, LED bulbs, and other lighting applications that require a wide input voltage range.
