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.
Finally, an onboard operational transconductance amplifier allows
for various configurations, including constant output current working
mode or traditional voltage regulation.
Features
• High Frequency Operation from 50 kHz up to 1.0 MHz
• Selectable Minimum Switching Frequency with "3% Accuracy
• Adjustable Deadtime from 150 ns to 1.0 ms
• Startup Sequence via an Adjustable Soft−Start
• Brown−Out Protection for a Simpler PFC Association
• Latched Input for Severe Fault Conditions, e.g. Overtemperature
or OVP
• Timer−Based Input with Auto−Recovery Operation for Delayed
Event Reaction
• Enable Input for Immediate Event Reaction or Simple ON/OFF
Control
• Operational Transconductance Amplifier (OTA) for Multiple
Feedback Loops
• VCC Operation up to 20 V
• Low Startup Current of 300 mA Max
• Common Collector Optocoupler Connection
• Internal Temperature Shutdown
• B Version Features 10 V VCC Startup Threshold for Auxiliary
Supply Usage
• Easy No−Load Operation and Low Standby Power Due to
Programmable Skip−Cycle
• These are Pb−Free Devices*
Typical Applications
• LCD/Plasma TV Converters
• High Power Ac−DC Adapters for Notebooks
• Industrial and Medical Power Sources
• Offline Battery Chargers
