LM5141QRG Synchronous Buck Converter Evaluation Module

Overview

TopologyBuck Converter
Input voltage5.5-42 V
Switching frequency2000-2400 kHz
Output 15 V / 5 A

Description

The LM5141-Q1 is a synchronous buck controller,intended for high voltage wide VIN step-downconverter applications. The control method is basedon current mode control. Current mode controlprovides inherent line feed-forward, cycle-by-cyclecurrent limiting, and ease of loop compensation. TheLM5141-Q1 features slew rate control to simplify thecompliance with the CISPR and Automotive EMIrequirements.The LM5141-Q1 has two selectable switchingfrequencies, 2.2 MHz and 440 kHz, and Gate Driverswith Slew Rate Control, for reduced conducted EMI.

Features

The EVM supports the following features and performance capabilities:

  • The LM5141-Q1 is Qualified to AEC-Q100 Grade 1 (–40ºC to +125ºC Operating JunctionTemperature)
  • VIN 5.5 to 42 V
  • Fixed 5-V output, or Adjustable From 1.5–15 V
  • Shutdown mode IQ: 10 μA
  • Low IQ Standby: 42 μA Typical (Output in Regulation, No Load)
  • Fixed 2.2 MHz, or 440 kHz Oscillator Frequency
  • Oscillator Can Shift From the Fundamental With a Resistor From the RT Pin to Ground, or an Analog
  • Voltage of 0 V to 0.6 V
  • The Internal Oscillator can be Synchronized to an External Clock
  • Spread Spectrum
  • EN Enable Output
  • Hiccup Mode for Sustained Overload
  • Power Good
  • Gate Drive With Slew Rate Control
  • Diode Emulation or Forced Pulse-Width Modulation
