STMICROELECTRONICS L6599D High-Voltage Resonant Controller
The L6599 is a high-voltage resonant controller designed for resonant half-bridge topology. It features a 50% duty cycle, variable frequency control up to 500 kHz, and burst-mode operation at light load. Incorporating an integrated bootstrap diode, it supports high efficiency, soft-switching, and synchronized gate driving for applications like LCDs, PDP TVs, desktop PCs, and telecom SMPS. Suitable for high-frequency operation with protections including UVLO, OCP, and line sensing, the IC simplifies power regulation with programmable oscillator and thermal management.
