NCP1395A/B  
High Performance Resonant  
Mode Controller  
The NCP1395A/B offers everything needed to build a reliable and  
rugged resonant mode power supply. Its unique architecture includes  
a 1.0 MHz Voltage Controller Oscillator whose control mode brings  
flexibility when an ORing function is a necessity, e.g. in multiple  
feedback paths implementations. Protections featuring various  
reaction times, e.g. immediate shutdown or timer−based event,  
brown−out, broken optocoupler detection etc., contribute to a safer  
converter design, without engendering additional circuitry  
complexity. An adjustable deadtime also helps lowering the  
shoot−through current contribution as the switching frequency  
increases.
