HIGH VOLTAGE SMART BALLAST CONTROLLER

The L6572 is a high voltage half-bridge driver for current regulation, quasi-self-oscillating ballast.\nIt contains all functions that are needed to preheat the filaments, to ignite and to operate a fluorescent lamp.\nDuring normal operation of the lamp, the ballast operates either with the nominal 600 V half-bridge driver\nIntegrated bootstrap diode\nFailure protection logic\nProgrammable deadtime\nProgrammable preheated start\nTwo-step dimming with programmable dimmed current\nThermal powerboost\nClosed loop control operation;
