Description
BP5152HC is a high current precision Linear LED
Driver integrated with High Voltage regulation
switchers and JFET supply, specially designed for
AC line LED strings forwarded with high voltage
and low current.
In application, it supports a quite small BOM
benefit from no ECAP and no Magnetics, compile
with EMI and safety standard.
BP5152HC can drive precision constant current
by option of an external resistor, and set up the
LED strings in group linear compile with THD
performance. Typical 40mA LED current is
optimized for 220V line voltage.
BP5152HC invite an external resistor to fulfill the
line regulation and adjust the output current
following input voltage.

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.
Note 3: Human Body mode, 100pF capacitor discharge on 1.5KΩ resistor

Application Information
BP5152HC is designed for linear driving LED
strings with high forward voltage low LED current
in line condition.
1 Supply
After system power on, the chip is supplied by
JEFT through D, starting work once voltage on D
above 10V.
LED working slots in every main cycles with
purpose of output lm maintenance and LED
availability improvement. For different application,
the forward voltage should match the input
voltage to obtain higher efficiency, like 110V and
220V respectively.
3 Current configuration
BP5152HC supports high precision LED current
set by external resistors.
2 Operation principle
Current for LED string defined as
BP5152HC auto adjust the LED strings in
working according to line voltage and extend the
