1. Reversed polarity at the input power will damage the driver. The input ground must not be connected to the negative output.
2. Leave the pin VADJ opened if not used, grounding VADJ will shut the driver off, connecting VADJ to +Vin will damage the driver.
3. Maximum output open voltage is equal to input voltage.

Resistive Dimming Control
A simplified dimming control can be achieved using a variable resistor connected between VADJ and GND. Capacitor CADJ
is optional, it is installed to limit AC mains interference and high frequency noise. The recommended value of CADJ is
0.22µF.
NOTE: Typical error is ±10% with resistive dimming control
The output current is given by:
Ioutnom ≈
Iout x Radj
(Radj + 50K)
If RADJ is between 0 and 2M ohm, the maximum adjustment
range of Iout is 25% to 90% (for Vin – Vout < 20V)

Output Current Adjustment by PWM Control:
Driving VADJ Directly
A Pulse Width Modulation (PWM) signal with a duty cycle DPWM can be applied to the ADJ pin as shown below.
The output current is given by:
Iout ≈ Ioutnom x DPWM

Driving VADJ Via Open Collector Transistor
The VADJ can also be driven via an open collector transistor as shown below.
The diode and resistor serve to suppress any possible high amplitude negative voltage spikes to the VADJ input resulting
from the collector to emitter capacitance of the transistor. Any negative voltage spikes will cause errors in output current
and/or unstable driver operation.

Driving the VADJ from a Microcontroller
The VADJ can be driven from an open drain output of a microcontroller as shown below. The diode and resistor serve to
suppress any possible high amplitude negative voltage spikes to the VADJ input resulting from the drain to source
capacitance of the FET. Any negative voltage spikes will cause errors in output current and/or unstable driver operation.
