BP2328DJ
BP2328DJ
Non-isolated Buck APFC Offline LED Driver
Description
The BP2328DJ 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 BP2328DJ integrates a 650V power MOSFET.
With few external components, the LED output current
can be precisely controlled.
The BP2328DJ utilizes patent pending 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 BP2328DJ 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.
