Power chip

The NCP1076A and NCP1076B products integrate a fixed frequency current mode controller with 700 V MOSFETs. It has two different pin outputs, adopts very common PDIP™7 encapsulation, highly integrated, including soft start, frequency dithering, short circuit protection, skip cycle, maximum peak current set point, slope compensation and dynamic self-power supply ( No auxiliary winding required). Unlike other monolithic solutions, the NCP1076A and NCP1076B are noiseless: during normal load operation, the part switches at a usable frequency (65 or 100 kHz). When the demand for output power disappears, the IC automatically enters frequency foldback mode, providing excellent efficiency at light loads. When power demand decreases further, it enters skip mode, reducing standby power consumption to no-load conditions. Protection features include: timers to detect overload or short circuit events, overvoltage protection with automatic recovery. AC input line voltage detection prevents severe runaway under low input voltage conditions (brownout) as well as over high input line (AC line overvoltage protection). This also enables the overpower protection to compensate for any internal delays at high input voltage conditions, optimizing the maximum output current capability. To improve standby performance, connecting an auxiliary winding stops DSS operation, helping to reduce input power consumption on the high line to less than 50 mW.

The FAN3213 and FAN3214 dual 4-A gate drivers deliver high peak current pulses with short switching intervals for driving N-channel enhancement mode MOSFETs in low-side switching applications. They both provide TTL input thresholds. Internal circuitry holds the output low until the supply voltage is within operating range, providing undervoltage lockout. In addition, these drivers feature matched internal propagation delays between the A and B channels, making them suitable for applications requiring tightly clocked dual gate drivers, such as synchronous rectifiers. This also enables the parallel connection of the two drivers, effectively doubling the current capability driving a single MOSFET. The FAN3213/14 drivers integrate the MillerDrive architecture for the final output stage. This bipolar-MOSFET combination provides high current during the Miller plateau phase of MOSFET turn-on/turn-off to minimize switching losses while providing rail-to-rail voltage swing and reverse current capability. The FAN3213 provides two inverting drivers and the FAN3214 provides two non-inverting drivers. Both feature standard 8-pin SOIC encapsulation.
