Series AMLD-Z  
Up to 1000mA | LED Driver  
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:  
[if PWM frequency < 300Hz,  
for 0.1<DPWM<1]  
Iout ≈

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.
