Application Notes

Output Current Adjustment by Variable Resistor

+Vout

- Vout

Control

-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

DPWM can be applied to the control pin, as shown:
