DESCRIPTION

NAME

NO.

Analog input used to set the reference of the linear controller. A 0-V to 1.5-V signal on ADIM sets the current

ADIM

is required.

COMP

7

I/O

Compensation for control loop. Connect a capacitor from the COMP pin to ground.

A capacitor to ground sets the length of the CDD pin charge pulse. Leave open if no phase dimmer

I

the MOSFET monitors MOSFET over-voltage. Add a capacitor to GND for filtering.

GDL

4

O

Gate drive for an external linear MOSFET.

GND

G

Chip ground return.

MULT

11

I

AC input to the multiplier. Tap a resistor divider off the rectified line to this pin.

TSNS

8

I

Thermal sense input. Connect to a resistor and NTC thermistor for thermal foldback.

VCC
