Pin Definitions and Functions

Pin No. Symbol Function

1

S

Supply voltage; external blocking capacitor necessary (see

Figure 4).

2

VSE Voltage Sense Input; non inverting with respect to voltage

compensation VCO; internal compared with the high accuracy

bandgap-reference (typ. 2.5 V).

3

OUT Output; NPN emitter follower output with an internal series resistor

of 1 kΩ; controlled by the potential of VCO or CCO; output voltage

is internally clamped therefore the output current is internally limited.

4

CSE Current Sense Input 1; connected to an internal voltage divider

(reference to the inverting input of the current OTA; see Figure 7).

5

GND Ground; reference potential unless otherwise specified.

6

CCO Current Compensation Output; internal series resistor to the

current-OTA output (typ. 1 kΩ); amplification internal temperature

compensated; current loop compensation can be done by an

external capacitor to GND.

7

VCO Voltage Compensation Output; internal series resistor to the

voltage-OTA output (typ. 1 kΩ); amplification internal temperature

compensated; voltage loop compensation can be done by an

external capacitor to GND.

8

CRE Current-OTA Reference Input; current sense reference input; non

inverting input of the current-OTA.
