개요

  • 본 제품은 Microchip사의 MCP1662 고전압 스텝업 전압 드라이버 모듈입니다.
  • PWM을 이용하여 LED 스트립을 디밍 제어할 수 있습니다.
  • 3.3V, 5V로 동작하며 MCU와 PWM 핀으로 통신합니다.

특징

  • MCP1662 MCU features

    The MCP1662 device is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with a constant current from a two- or three-cell alkaline or lithium Energizer®, or NiMH/NiCd, or one-cell Lithium-Ion or Li-Polymer batteries.

    The device integrates a 36V, 800 mW low-side switch, which is protected by the 1.3A cycle-by-cycle inductor peak current limit operation.

    How it works

    LED driver click has a power input and a PWM input, so the LED lights can be dimmed. It's a great choice for driving LED strips.
