NCP1398: High Performance Resonant Mode Controller with integrated high-voltage drivers

The NCP1398 is a high performance controller for half bridge LLC resonant converters. The integrated high voltage gate driver simplifies layout and reduces external component count. A unique architecture, which includes a 750 kHz Voltage Controlled Oscillator whose control mode permits flexibility when an ORing function is required allows the NCP1398 to deliver everything needed to build a reliable and rugged resonant mode power supply. The NCP1398 provides a suite of protection features with configurable settings to allow optimization in any application. This includes: auto-recovery and latch-off over-current protection, brown-out detection, open optocoupler detection, adjustable soft-start and dead-time.
