NCP1396A_10 Datasheet, PDF (1/25 Pages) ON Semiconductor – High Performance Resonant Mode Controller featuring High-Voltage Drivers

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
