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.
