NCP1396A

High Performance Resonant Mode Controller featuring High--Voltage Drivers

ON Semiconductor 

NCP1396A, NCP1396B

High Performance Resonant

Mode Controller featuring

High- Voltage Drivers

The NCP1396 A/B offers everything needed to build a reliable and

rugged resonant mode power supply. Its unique architecture includes

a 500 kHz Voltage Controlled Oscillator whose control mode brings

flexibility when an ORing function is a necessity, e.g. in multiple

feedback paths implementations. Thanks to its proprietary

high- voltage technology, the controller welcomes a bootstrapped

MOSFET driver for half- bridge applications accepting bulk voltages

up to 600 V. Protections featuring various reaction times, e.g.

immediate shutdown or timer- based event, brown- out, broken

opto- coupler 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.

Features

 High- frequency Operation from 50 kHz up to 500 kHz

 600 V High- Voltage Floating Driver

 Selectable Minimum Switching Frequency with 3% Accuracy

 Adjustable Deadtime from 100 ns to 2 ms.

 Startup Sequence via an 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

 Enable 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

 Internal Temperature Shutdown

 B Version features 10 V VCC Startup Threshold

 These are Pb- Free Devices

Typical Applications

 Flat Panel Display Power Converters

 High Power AC/DC Adapters for Notebooks

 Industrial and Medical Power Sources

 Offline Battery Chargers
