TPS40055 - Wide-Input Synchronous Buck Controller

Download the TPS40055 datasheet PDF. This datasheet also covers the TPS40054 variant, as both devices belong to the same wide-input synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

Description

The TPS4005x is a family of high-voltage, wideinput (8 V to 40 V), synchronous, step-down controllers.

Features

  • New products available.
  • LM5145 75-V synchronous buck controller with wide input voltage and duty cycle ranges.
  • LM5146 100-V synchronous buck DC/DC controller with wide duty-cycle range.
  • Operating input voltage 8 V to 40 V.
  • Input voltage feedforward compensation.
  • < 1% internal 0.7-V reference.
  • Programmable fixed-frequency up to 1-MHz voltage mode controller.
  • Internal gate-drive outputs for high-side and synchronous N-channel.
