STMicroelectronics L6599A
The L6599A is an improved revision of the previous L6599. It is a double-ended controller specific to series-resonant half bridge topology. It 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.| Part No. | L6599A |
