L6699DTR ST AC-DC Controllers

The L6699DTR is an offline half-bridge resonant controller from STMicroelectronics in 16-pin SOIC package, designed for high-efficiency resonant converters with enhanced protection features. For selection, verify supply voltage from 8.85V to 16V, start-up voltage of 10.7V, switching frequency from 60kHz to 235kHz, 50% duty cycle, fault protection with current limiting, soft-start control feature, and operating temperature from -40°C to +150°C. Features include adaptive dead-time control for optimal efficiency, anti-capacitive mode protection for safe operation, burst mode operation for standby power reduction, and precise frequency control for resonant tank optimization. Ideal for high-efficiency AC-DC power supplies for LCD TVs and PDP TVs, desktop computer and server PSUs, battery chargers for electric vehicles, LED drivers, and any medium-to-high power LLC resonant converter requiring high efficiency through zero-voltage switching (ZVS) with low EMI signature.
