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:
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.
Features
• High−Frequency Operation from 50 kHz up to 500 kHz
• 600 V High−Voltage Floating Driver
• Adjustable Minimum Switching Frequency with ±3% Accuracy
• Adjustable Deadtime from 100 ns to 2 ms.
• Startup Sequence Via an Externally Adjustable Soft−Start
• Brown−Out Protection for a Simpler PFC Association
• Latched Input for Severe Fault Conditions, e.g. Over Temperature
or OVP
• Timer−Based Input with Auto−Recovery Operation for Delayed
Event Reaction
• Latched Overcurrent Protection
• Disable Input for Immediate Event Reaction or Simple ON/OFF
