AF1937K - White LED Step UP Converter

Download the AF1937K datasheet PDF. This datasheet also covers the AF1937K-Alfa variant, as both devices belong to the same white led step up converter family and are provided as variant models within a single manufacturer datasheet.

Description

The AF1937K is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current.

The device can drive up to 27 LEDs from a 5V supply.

Additional feature include output voltage limiting when LEDs are disconnected.

Features

  • Inherently Matched LED Current Drives Up to 27 LEDs from a 5V Supply 36V Rugged Bipolar Switch Fast 1.2MHz Switching Frequency VOUT(MAX)=30V.
