DESCRIPTION

Description

OVERVIEW

Product Overview

This device is an automotive-grade boost controller from Texas Instruments in a SOP package. It uses external power switches and an inductor to step up a lower input voltage to a higher output voltage, serving vehicle electronics that need supply above the battery voltage. As a controller rather than an integrated switcher, its output capability depends on external component selection. Switching frequency, input/output ranges and protection features must be checked in the original datasheet.

APPLICATIONS

Applications

  • High-voltage supply for automotive audio amplifiers.
  • Boost supply for LED driving.
  • Bias supply above battery voltage in automotive electronics.
FEATURES AND BENEFITS

Features and Benefits

  • Automotive-grade device for vehicle power designs.
  • Controller architecture with external switch and inductor.
  • Provides step-up conversion from input to output.
  • SOP package is easy to solder and rework.
ADDITIONAL DETAILS

Additional Details

Before purchasing, confirm the temperature grade and package for the suffix, and check whether external switches, inductors and compensation components are required. Actual power capability depends on external selection; design with the original datasheet.

Verify product details against the manufacturer datasheet before purchase.
