BP2327A
Non-isolated Buck APFC LED Driver
Description
The BP2327A is a high precision non-isolated buck
APFC LED driver, specially designed for universal
mains with constant current control. The driver with
on-chip PFC circuit achieves high power factor, low
THD and high efficiency.
The BP2327A integrates a 650V power MOSFET,
utilizes patent pending floating ground structure, and
operates in Critical Conduction Mode. The switching
loss is reduced and the inductor is fully utilized. The
inductor current is sensed during the whole switching
cycle and limited cycle by cycle. With few external
components, it achieves high precision output
current, excellent line regulation and load regulation.
The BP2327A offers full of protection functions to
improve the system reliability, including LED load
open circuit protection, LED load short protection,
VCC under voltage protection, Current Sense
resistor open circuit protection, and over
temperature protection. 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 in
condition of over temperature.

Note 1: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. Under “recommended operating
conditions” the device operation is assured, but some particular parameter may not be achieved. The electrical characteristics table defines the operation
range of the device, the electrical characteristics is assured on DC and AC voltage by test program. For the parameters without minimum and maximum value
in the EC table, the typical value defines the operation range, the accuracy is not guaranteed by spec.
Note 2: The maximum power dissipation decrease if temperature rise, it is decided by TJMAX, θJA, and environment temperature (TA). The maximum power
dissipation is the lower one between PDMAX = (TJMAX - TA)/ θJA and the number listed in the maximum table.
