LEDD16_24 Series
Constant current power LED driver - Wide Input - Non-Isolated & Regulated
LED Driver
The LEDD16_24 is a high-efficiency series of step-down converters optimized to
driving high current LEDs. The device operates from an input of 7VDC to 30VDC
and provides an externally adjustable output current up to 1000mA and output
power up to 24 watts. Compact size of DIL16 allows designers to integrate this
driver together with LED module. UL94V-0 grade molded case with high grade
filling material provides excellent fire proof characteristics.

LEDD16_24 Series
Constant current power LED driver - Wide Input - Non-Isolated & Regulated
Output current adjustment by external DC control volta-
In this application, the LED modules of
each LED drivers should be independent
from electrical connection to the others
and input power - this is to prevent the
damaging to LED drivers also to avoid the
un-necessaried interference among each
LED module driven by the LED driver.
Thermal feedback circuit
The selection of components for the thermal feedback circuit is not only dependent on the
choice of R2 and R3, but also on the amount of heat sink area required to extract heat from the
LEDs. To maximize the light output at high ambient or operating temperature conditions, the
LEDs must have a sufficient thermal extraction path, otherwise the thermal control circuit will
effect current drive reduction in non-optimal conditions. The thermal control threshold point is
set by adjusting R2. For this design, three values (33k, 22k and 10k) were evaluated. These values
were chosen to give break points at approximately 25°C, 40°C and 60°C.
Note that the light output will not continually dim to zero - the thermal control is applying DC
control to the ADJ pin and therefore has a dimming ratio from maximum Current of approxi-
mately 5:1. Once the reduced DC level goes below the shutdown threshold of around 200mV, the
LED drive current will fall to zero and the LEDs will be extinguished. The slope of the current re-
duction is determined by the beta value of the thermistor. The larger the beta value, the sharper
will be the resultant current control response. The slope of the current reduction is also affected
by Q1‘s base emitter voltage (VBE) variation with temperature.

2. Pin pitch and length tolerance: 0.35 ( 0.014)
3. Case Tolerance: 0.5 ( 0.02)
Note
1. Reversed power source damages the circuit, No connection is allowed between
input ground and output.
2. DO NOT operate the driver over 24W output.
3. Leave pin VADJ open if not in use,ground pin to shut down the converter.
Connecting Vadj to Vin damages the circuit.
4. Maximum output open voltage is equal to input voltage
5. Input filter components (C1, L, C2) are used to help meet conducted emissions
requirement for the module.
6. For the compliance with IEC61000-4-5, a TVS is thus recommended to be
installed in from of the input filter, the reference model: 3.0SMCJ24A or
SMCJ24A (TVS Max Clamping Voltage @ Max Peak Pulse, Current VC (V) ≤ 40V)
