LM2592HV

Overview

The LM2592HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 2A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version.

  • 3.3V, 5V, and adjustable output versions
  • Adjustable version output voltage range, 1.2V to 57V ± 4% max over line and load conditions
  • Guaranteed 2A output load current
  • Available in 5-pin TO-220 and TO-263 (surface mount) Package
  • Input voltage range up to 60V
  • 150 kHz fixed frequency internal oscillator
  • On/Off control
  • Low power standby mode, IQ typically 90 µA
  • High Efficiency
  • Thermal shu
