Post regulation, dual N-Channel MOSFET Driver, Model NCP4330 features drive outputs for series FETs and free-wheeling synchronous FETs. It offers efficient means of deriving 3.3 V from 5 V power train while not requiring additional windings or terminals on power supply's power transformer. Secondary ac signal directly feeds NCP4330 to minimize power dissipation. Driver includes soft switching,... Read More
Featuring 1.6 x 0.8 mm footprint, Series ESD5Z provides single line protection to portable and battery-operated applications. Available in 5 models, units clamp fast rising ESD pulses, preventing damage to voltage-sensitive components on board. Input waveform of 30 kV per IEC61000-4-2 standard can be clamped to less than 7 V in nanoseconds. Devices can dissipate up to 200 W with 8 x 20 µsec... Read More
Fixed-frequency, current-mode NCP1653 drives continuous conduction mode boost converters with power needs from 100 W to 3 kW. It can also operate with output voltage tracking input voltage, called follower boost. Designed for PFC boost circuits in power ranges up to 300 W, NCP1601 operates in fixed-frequency discontinuous conduction mode and/or variable frequency critical conduction mode. Both... Read More
Current Mode Controllers Series NCP1230 and NCP1231 allow power supply designers to shut-down power factor correction stage in light or no-load conditions. Units offer cycle skipping at light loads, internal ramp compensation, and frequency dithering. Both series are available in 65, 100, and 133 kHz frequency options. Series NCP1230 integrates 2.5 ms soft-start, while Series NCP1231 offers... Read More
Self-contained BERS(TM) NIS6111 couples high-speed comparator and MOSFET driver with power MOSFET to create diode with same forward-drop characteristics as MOSFET, eliminating heat sinks. It is capable of blocking up to 24 V and has typical forward voltage drop of 0.1 V at forward current of 20 A. Offered in 9 x 9 mm QFN package, Model NIS6111 can be used as oring diode used in servers and... Read More
