LM27402 Overview

Key Specifications

Package: TSSOP
Mount Type: Surface Mount
Pins: 16
Max Frequency: 1.35 MHz

Description

The LM27402 is a voltage-mode, synchronous, DC/DC step-down controller with lossless inductor DCR current sensing capability. Sensing the inductor current eliminates the need to add resistive powertrain elements, which increases overall efficiency and facilitates accurate, continuous current sensing.

Key Features

  • 1 Wide Input-Voltage Range of 3 V to 20 V
  • Inductor DCR or Shunt Resistor Based Overcurrent Protection
  • 0.6-V Reference With ±1% FB Accuracy Across Full –40°C to 125°C Junction Temperature Range
  • Switching Frequency from 200 kHz to 1.2 MHz
  • Output Voltage as High as 95% of Input Voltage
