EV1765

Description

EV1765_S0_R2 is a 70V/240mA LED driver EVB based on JW1765.

The JW1765 is a constant current LED controller with high current accuracy which applies to single stage step-down power factor corrected LED drivers.

JW1765 is supplied from the output directly, and auxiliary winding is not needed, which can largely reduce the BOM cost and short the development process.

JW1765 has multi-protection functions which largely enhance the safety and reliability of the systemincluding VCC over-voltage protection, VCC UVLO, short circuit protection, LED open protection,cycle-by-cycle current limit and over-temperature protection.

Features

◆No auxiliary winding

◆Critical conduction mode
◆High efficiency over wide operating range
◆Cycle-by-cycle current limit
◆LED short protection
◆LED open protection
◆Over-temperature protection
◆Compact SOT23-6 package
