Voltage-Current Regulator TLE 4305 Features - - - - - - - - - - - - Wide supply voltage operation range Wide ambient temperature operation range Minimized external circuitry High voltage regulation accuracy High current limit regulation accuracy Low temperature drift Independent voltage- current-loop pensation Internal fixed amplification Fully temperature pensated current- and voltage OTA (operational transconductance amplifier) SMD package Industrial type Green Product (Ro HS pliant) Functional Description The TLE 4305 G is specifically designed to control the output voltage and the output current of a switch mode power supply. Independent pensation networks for the voltage- and for the current-loop can be realized by external circuitry. The device contains a high accuracy bandgap reference voltage, two operational trans conductance amplifier (OTA), an opto-coupler driver output stage and an high-voltage bias circuit. The device is based on Infineons double isolated power line technology DOPL which allows to produce high precision bipolar voltage regulators with breakdown voltages up to 45 V. ..

Voltage Sense Input; non inverting with respect to voltage pensation VCO; internal pared with the high accuracy bandgap-reference (typ. 2.5 V). 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. Current Sense Input 1; connected to an internal voltage divider (reference to the inverting input of the current OTA; see Figure 7). Ground; reference potential unless otherwise specified. Current...
