BP2335J
Non-isolated Buck APFC LED Driver
Description
The BP2335J is a high precision non-isolated buck
driver with active PFC, specially designed for universal
input offline constant current LED lighting. The driver
with on-chip PFC circuit achieves high power factor
and low THD. Operating in critical conduction mode,
the power MOSFET switching loss is reduced and the
inductor is fully utilized.
The BP2335J integrates a 550V power MOSFET.
With few external components, the LED output
current can be precisely controlled.
The BP2335J utilizes patented floating ground
structure. The inductor current is sensed during the
whole switching cycle. So it achieves high precision
output current control, and excellent line regulation and
load regulation.
The BP2335J utilizes patented start up technology
with HV JFET. So it achieves fast start up, reduce
count of external components, and realize smaller
form factor.
Features
Fast start up and power supply with HV JFET
Integrated with 550V Power MOSFET
Active PFC for High Power Factor and Low THD
System Efficiency up to 95%
±3% LED Output Current Accuracy
Excellent Line and Load Regulation
Critical Conduction Mode Operation
Ultra Low (300uA) Operating Current
LED Short/Open Protection
Current Sensing Resistor Open Protection
Cycle by Cycle Current Limit
VCC Under Voltage Protection
Auto Fault Recovery
Thermal Regulation Function
Applications
LED retrofit lamps, Bulb, Spot Light, GU10/E27
LED PAR30, PAR38 Lamp
LED tube, LED String
Other LED Lighting
The BP2335J offers rich protection functions to
improve the system reliability, including LED open
circuit protection, LED short circuit protection, VCC
under voltage protection, CS resistor open circuit
protection and cycle by cycle current limit. All the
protection functions are auto-recovery. The system
reliability is further improved by the thermal regulation
function. The output current is reduced when the driver
is over temperature.
