OB3341S
Buck LED Driver with High PF
GENERAL DESCRIPTION
The OB3341S is a high power factor, monolithic
Buck regulator with advanced features to provide
high efficiency control and high accuracy constant
current output for LED lighting applications.
OB3341S integrates a 2A MOSFET to decrease
physical volume. It adopts constant on time control
for power factor correction (PFC), zero current
detectors (ZCD) to ensure quasi-resonant valley
turn-on for high efficiency operation.
OB3341S offers good protection coverage
including VCC under voltage lockout (UVLO), VCC
over voltage protection, cycle-by-cycle current
limiting, over temperature protection, COMP pin
floating protection and LED open/short protection.
OB3341S is provided with DIP8 package.
FEATURES
Buck topology power switching with single
stage PFC (PF>0.9)
Integrated 2A 600V MOSFET
Quasi-resonant valley turn-on mode
operation to achieve high efficiency (>90%)
High accuracy output current (±3%)
LED open/short protection
Low power dissipation at LED short
Ultra-low start-up current (typical 5uA)
APPLICATIONS
LED lighting
Tube lighting
PAR lighting
Bulb lighting
