YB1520 - High Power Step-up DC-DC Converter

Datasheet Summary

Description

The YB1520 is a step-up DC-DC converter; operates as current source to drive up to 9 white LEDs in series or 30 white LEDs in parallel/series configuration.

Series connecting of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.

Features

  • Built-in internal switch Adjustable output voltage up to 35V 2.7V to 16V input range.

www.DataSheet4U.com YB1520 High Power Step-up DC-DC Converter, White LED Driver Description The YB1520 is a step-up DC-DC converter; operates as current source to drive up to 9 white LEDs in series or 30 white LEDs in parallel/series configuration. Series connecting of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. The light intensity of these LEDs is proportional to the current passing through them. The YB1520 switches at a fixed frequency of 700KHz, allowing the use of tiny, low profile inductors and capacitors to minimize footprint and cost in space consideration applications for cellular phone backlighting or other hand held equipment.
