Control

Output Current Adjustment by PWM

A Pulse Width Modulated (PWM) signal with duty cycle DPWM can be applied to the control pin.

The output current can be determined using the equation : Iout = Rated Max I x Dpwm

Dpwm = PWM duty cycle

1. Add suffix ‘-W’ for wired version, e.g. LDU5660S500-W, or ‘-WD’ for wired version with dimming function e.g. LDU5660S500-WD.
