NCP1397A/B, NCV1397A/B
High Performance Resonant
Mode Controller with
Integrated High-Voltage
Drivers
The NCP1397 is a high performance controller that can be utilized
in half bridge resonant topologies such as series resonant, parallel
resonant and LLC resonant converters. It integrates 600 V gate
drivers, simplifying layout and reducing external component count.
With its unique architecture, including a 500 kHz Voltage Controlled
Oscillator whose control mode permits flexibility when an ORing
function is required, the NCP1397 delivers everything needed to build
a reliable and rugged resonant mode power supply.
The NCP1397 provides a suite of protection features with
configurable settings to optimize any application. These include:
autoârecovery or fault latchâoff, brownâout, open optocoupler,
softâstart and shortâcircuit protection. Deadtime is also adjustable to
overcome shoot through current.
