Application Notes
Output Current Adjustment by Variable Resistor
+Vout
- Vout
-Vin
By connecting a variable resistor between control
and GND, simple dimming can be achieved.
Capacitor is optional for HF noise rejection.
Recommended value is 0.22 µF.
LDU
The output current can be determined using the equation:
Iout nom x R
(R + 200 k)
Iout nom x R
For LDU08-24
Iout =
For LDU48
Iout =
(R + 50 k)
Where the value of R is between 0 and 2 MΩ, the
maximum adjustment range of output current is 25% to 90%
(For Vin-Vout, LDU08 & 24: <20 VDC, LDU48: <30 VDC )
Output Current Adjustment by DC Voltage
Control Voltage Range: 0.3 V to 1.25 VDC

The output current is given by:

Output Current Adjustment by PWM
Directly driving control input
A Pulse Width Modulated (PWM) signal with duty cycle
