JW1769B Datasheet Offline Step-down Led Regulator

Manufacturer: JoulWatt

Overview: JW1769A/B/C Parameters Subject to Change Without Notice Offline Step-down LED Regulator With PFC and High Voltage.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The JW®1769A/B/C is a constant current LED regulator with high current accuracy which applies to single stage step-down power factor corrected LED drivers.600V power MOS is integrated, which can significantly simplify the design of LED lighting system.

High accuracy of output current is achieved by sampling the output current directly.

Critical conduction mode operation reduces the switching losses and largely increases the efficiency.

Key Features

  • No auxiliary winding 600V high voltage MOSFET integrated EMI friendly High current accuracy of line and load regulation High power factor with low output current-ripple Critical conduction mode High efficiency over wide operating range Cycle-by-cycle current limit LED short protection LED open protection Over-temperature protection Compact SOP7 package.
