Up to 700mA | LED Driver

Output Current Adjustment by PWM Control:

Driving VADJ Directly

A Pulse Width Modulated (PWM) signal with a duty cycle of DPWM can be applied directly to VADJ pin as shown below.

The output current is given by:

x DPWM [for 0.01<DPWM<1]

Ioutnom = 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.

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.
