Description

The IL300 Linear Optocoupler consists of an AlGaAs

IRLED irradiating an isolated feedback and an output

PIN photodiode in a bifurcated arrangement. The

feedback photodiode captures a percentage of the

LED’s flux and generates a control signal (I

) that

can be used to servo the LED drive current. This tech-

nique compensates for the LED’s non-linear, time,

and temperature characteristics. The output PIN pho-

todiode produces an output signal (I

) that is linearly

related to the servo optical flux created by the LED.

The time and temperature stability of the input-output

coupler gain (K3) is insured by using matched PIN

photodiodes that accurately track the output flux of

the LED.

IL300 VISHAY Vishay Semiconductors The isolated amplifier provides the PWM control signal which is derived from the output supply voltage. Figure 16 more closely shows the basic function of the amplifier. The control amplifier consists of a voltage divider and a non-inverting unity gain stage. The TDA4918 data sheet indicates that an input to the control amplifier is a high quality operational amplifier that typically requires a +3.0 V signal.
