Overview
JW1769A/B/C Parameters Subject to Change Without Notice Offline Step-down LED Regulator With PFC and High Voltage MOSFET DESCRIPTION The JW1769A/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.
JW1769A/B/C is supplied from the output directly, and auxiliary winding is not needed.
JW1769A/B/C has multi-protection functions which largely enhance the safety and reliability of the system, including 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 600V high voltage MOSFET integrated EMI fr...
