XL1509A-ADJE1

Component

adjustable buck converter150 kHz50 V inputSOP-8non-synchronous

XL1509A-ADJE1 is an adjustable SOP-8 buck regulator for stepping 4.5 V to 50 V inputs down to outputs from 1.23 V to 48 V.

Best for

  • Adjustable low-cost buck supplies
  • Industrial and communications equipment
  • Input rails up to 50 V

Avoid if

  • A synchronous converter is required
  • Very high switching frequency is needed
  • Output current capability must be guaranteed at 2 A across all input voltages without thermal validation

Check before use

  • Input surge margin versus the 60 V absolute maximum rating
  • Inductor saturation current and diode voltage/current ratings
  • Thermal dissipation of the SOP-8 package
  • Feedback-divider values for the required output voltage
