NCP1397B شرح
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:
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
Control
VCC Operation up to 20 V
Low Startup Current of 300 mA
1 A/0.5 A Peak Current Sink/Source Drive Capability
Common Collector Optocoupler Connection for Easier ORing
Optional Common Emitter Optocoupler Connection
Internal Temperature Shutdown
NCV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
