L6599AD - RESONANT CONTROLLER, SOIC-16

Descrição geral do produto
The L6599AD is an improved high-voltage Resonant Controller provides 50% complementary duty cycle, the high-side switch and the low-side switch are driven ON/OFF 180° out-of-phase for exactly the same time. Output voltage regulation is obtained by modulating the operating frequency. A fixed dead-time inserted between the turn-OFF of one switch and the turn-ON of the other guarantees soft-switching and enables high-frequency operation. To drive the high-side switch with the bootstrap approach, the IC incorporates a high-voltage floating structure able to withstand more than 600V with a synchronous-driven high-voltage DMOS that replaces the external fast-recovery bootstrap diode. The IC enables the designer to set the operating frequency range of the converter by means of an externally programmable oscillator. At light load the IC may enter a controlled burst mode operation that keeps the converter input consumption to a minimum.
