STMicroelectronics | L6699D

The L6699D is a 16 V, 245 KHz enhanced high voltage resonant controller and is available in SOIC-16 package.

This IC enables the user to set the operating frequency range of the converter by means of a high-accuracy externally programmable oscillator.

Features:

• Symmetrical duty cycle, variable frequency control of resonant half bridge
• Self-adjusting adaptive deadtime
• High-accuracy oscillator
• 2-level OCP: frequency-shift and immediate shutdown
• Interface with PFC controller
• Anti-capacitive-mode protection
• Burst-mode operation at light load
• Input for brownout protection or power-on/off sequencing
• “Safe-start” procedure prevents hard switching at startup
• 600 V rail compatible high-side gate driver with integrated bootstrap diode and high dv/dt immunity
• -300/800 mA high-side and low-side gate drivers with UVLO pull-down

Applications:

• SMPS for LCD TVs, desktop and AIO PCs, servers, Telecom power
• AC-DC adapter, open frame SMPS
