High Performance Resonant  
Mode Controller with  
Integrated High-Voltage  
Drivers  
www.onsemi.com  
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:  
auto−recovery or fault latch−off, brown−out, open optocoupler,  
soft−start and short−circuit protection. Deadtime is also adjustable to  
overcome shoot through current.
