1.2 Features

The LM5152EVM-BST has the following features:

  • Input voltage range from 2.5 V to 36 V (7 V to start up)
  • Internal low leakage current high-impedance feedback resistors with programmable output voltage
  • Operating frequency of 440 kHz with externally clock synchronization up or down by 20%
  • Bypass mode operation when VIN is greater than VOUT
  • Selectable forced PWM (FPWM), skip mode, or diode emulation using the MODE pin
  • High power conversion efficiency across a wide operating range
  • Cycle-by-cycle peak current limiting
  • Optional frequency dithering for improved EMI performance
  • Boost STATUS indicator
  • Programmable soft-start time
  • Programmable line undervoltage lockout (UVLO)
