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 Controller 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
• V_CC Operation up to 20 V
• Low Startup Current of 300 mA
• 1 A / 0.5 A Peak Current Sink / Source Drive Capability
