NCP1396BDR2G

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
