Power chip

The NCP1397 is a high-performance controller for half-bridge resonant topologies such as series resonant, parallel resonant and LLC resonant converters. It integrates a 600 V gate driver, which simplifies layout and reduces external parts count. The unique architecture of the NCP1397, including a 500 kHz voltage-controlled oscillator whose control mode allows flexibility where OR operations are required, provides everything needed to build a reliable and robust resonant mode power supply. The NCP1397 provides a suite of protection functions with configurable settings to optimize any application. These include: auto recovery or fault latching, under voltage, open optocoupler, soft start and short circuit protection. Dead time is also adjustable to overcome shoot through current. NCV1397 Available in Automotive Qualified Version (AEC-Q100/PPAP)
