Description
The IX9915 integrates an error amplifier with a precision reference and a 350V Darlington transistor in a single package. The error amplifier can be operated from 1.3V to 12.5V over the operational temperature range. The breakdown voltage of the Darlington transistor is 350V.
The integrated combination of a 4-terminal 431 type shunt regulator with a high voltage Darlington transistor is ideal for use in LED lamp bleeder control circuits.
