L6599AD Power Supply Controller Resonant Converter Controller 16-SO

L6599AD Power Supply Controller for Resonant Converter

The L6599AD Power Supply Controller is the perfect solution for efficient power regulation in your electronic devices. This advanced controller is specifically designed for series-resonant half bridge topology, offering improved features over its predecessor, the L6599. With a complementary duty cycle of 50%, the high-side switch and low-side switch are driven ON/OFF 180° out-of-phase, resulting in optimal power regulation.

Efficient Power Regulation with Soft-Switching Technology

One of the standout features of the L6599AD is its ability to modulate the operating frequency for output voltage regulation. Combined with fixed deadtime, this controller enables soft-switching and high-frequency operation. The IC incorporates a high-voltage floating structure capable of withstanding more than 600V, thanks to the synchronous-driven high-voltage DMOS that replaces the need for an external fast-recovery bootstrap diode.

Advanced Features for Reliable Power Supply Control

The L6599AD features a programmable oscillator that allows for a wide operating frequency range, providing flexibility for your converter. Additionally, it offers a not-latched active-low disable input with current hysteresis, which can be useful for power sequencing or brownout protection. The current sense input for OCP with frequency shift allows for a delayed shutdown with automatic restart. Furthermore, the IC includes a higher-level OCP that latches off the IC if the first-level protection is insufficient to control the primary current, ensuring complete protection against overload and short-circuits.
