Low-Dropout High-Power LED Driver
CN5612
General Description:
The CN5612 current regulator operates from a 2.7V
to 6V input voltage range and delivers a constant
current that is up to 1.2A to high-brightness LEDs,
including high-brightness white LED. The LED
current of CN5612 can be adjusted from 30mA to
1.2A by using an external resistor. An on-chip pass
element minimizes external components while
providing ±8% output current accuracy. Additional
features include over temperature protection, LED
short and open protection.
The CN5612 is available in a thermally enhanced
5-pin TO252 package.

Function Description
No Connnection.
Positive Supply Voltage. VDD is the power supply to the internal circuit.
Ground Terminal.
LED Cathode Connection Pin.
Constant LED Current Setting Pin. The constant LED current is set by
connecting a resistor RISET from this pin to VDD. The LED current is
determined by the following equation:
Iout = 910VRISET
Where, Iout is in ampere(A)
RISET is in ohm(Ω)
Absolute Maximum Ratings
All Terminal Voltage……………0.3V to 6.5V
Operating Temperature…............40to 85
Thermal Resistance(Junction to case) .....10/W
Maximum Junction Temperature…...150
Storage Temperature……….........65to 150
Lead Temperature(Soldering)…….....300
Stresses beyond those listed under ‘Absolute Maximum Ratings’ may cause permanent damage to the device. These are stress
ratings only and functional operation of the device at these or any other conditions above those indicated in the operational
sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect
device reliability.
