TPS61151 - Dual-Output Boost WLED Driver

This page provides the datasheet information for the TPS61151, a member of the TPS61150 Dual-Output Boost WLED Driver family.

Datasheet Summary

Description

The TPS6115x is a high-frequency boost converter with two regulated current outputs for driving WLEDs.

Each current output can be individually programmed through external resistors.

There is a dedicated selection pin for each output so the two outputs can be turned on separately or simultaneously.

Features

  • 1 2.5-V to 6-V Input Voltage Range.
  • Two Outputs Each up to 27 V.
  • 0.7-A Integrated Switch.
  • Built-In Power Diode.
  • 1.2-MHz Fixed PWM Frequency.
  • Individually Programmable Output Current.
  • Input-to-Output Isolation.
  • Built-In Soft Start.
  • Overvoltage Protection.
  • Up to 83% Efficiency.
  • Up to 30-kHz PWM Dimming Frequency 2.
