Description
Constant
The RCDE-48 series is a step-down constant current source designed for driving high power LED
applications from 12V, 24V or 48V nominal input voltages. 350, 700 or 1050mA output currents are
available as standard. The input voltage range is from 6V up to 60VDC with UVLO. These high efficiency
buck drivers have digital PWM and/or analog voltage dimming control which is capable of being
controlled by 3.3V logic. The dimming input can also be used as an CTRL pin. Typical application is a
48V powered lighting solution for up to 15 high brightness LEDs in series.

All LED Drivers may not be used without a load. They must be switched on the primary side only.
Noncompliance may damage the LED or reduce its lifetime.
Notes:
Note1: Efficiency is tested at nominal input and 15 LEDs (15 x VF 3VDC = 45VDC) at +25°C ambient

DROPOUT VOLTAGE
Dropout voltage is the smallest difference between a regulators input and its
output voltage, which is required to maintain regulation and enable the regulator
to provide rated output voltage or current.
+Vin
LED+
Vin
Vout
= input voltage
= output voltage
Example:
Vdropout = 3VDC max.
nLED = 11 LEDs
VF max. = 3VDC
Vin
Vout

Vdropout = dropout voltage
nLED = number of LEDs
VF max. = forward voltage
-Vin

Vdropout
Vout max. = Vin - Vdropout
Vin min. = 11 x 3+ 3
Vin min. = nLED x VF max. + Vdropout
