JW1531B - BUCK CC/CV Driver

Download the JW1531B datasheet PDF. This datasheet also covers the JW1531M variant, as both devices belong to the same buck cc/cv driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The JW®1531B/JW1531M is a constant voltage constant currentdriver with high accuracy.

JW1531M/JW1531B integrates high voltage power source, and can be supplied from line voltage directly, and auxiliary winding is not needed, which largely simplifies the system.

Key Features

  • No auxiliary winding.
  • Supplied from line voltage directly.
  • High current accuracy of line and load regulation.
  • Critical conduction mode.
  • High efficiency over wide operating range.
  • LED short protection.
  • Internal over-temperature protection.
  • SOP7 package.

JW1531M/JW1531B Parameters Subject to Change Without Notice DESCRIPTION The JW®1531B/JW1531M is a constant voltage constant currentdriver with high accuracy. JW1531M/JW1531B integrates high voltage power source, and can be supplied from line voltage directly, and auxiliary winding is not needed, which largely simplifies the system. Low standby consumption can be achieved with deep pulse frequency modulation. Critical conduction mode operation reduces the switching losses and largely increases the efficiency. JW1531M/JW1531B has multi-protection functions which largely enhance the safety and reliability of the system, including VCC over-voltage protection, VCC UVLO, LED short protectionand over-temperature protection.
