L6599N Description

Short technical summary and product information.

The STMicroelectronics L6599N is a high-voltage resonant controller IC, suitable for various power supply applications including LCD and PDP TVs, desktop PCs, entry-level servers, telecom SMPS, and AC-DC adapters. This device offers a 50% duty cycle with variable frequency control for resonant half-bridge configurations and supports operating frequencies up to 500 kHz.

 

Key features include a high-accuracy oscillator, two-level overcurrent protection (OCP) with frequency-shift and latched shutdown, and burst-mode operation at light loads. It also provides a non-linear soft-start for monotonic output voltage rise and a 600V-rail compatible high-side gate driver with integrated bootstrap diode and high dV/dt immunity. The L6599N is available in a 16-DIP package and operates within a temperature range of 0°C to 105°C.

 

This controller is not recommended for new designs. It requires a supply voltage between 8.85V and 16V and consumes a typical supply current of 3.5 mA. The through-hole mounting type simplifies integration into existing board designs.
