STMicroelectronics L6599AFD
The L6599AF is an improved revision of the previous L6599A. 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-ofphase for exactly the same time.| Part No. | L6599AFD |
