The NCP1366 provides a novel solution aimed at achieving output power levels from a few watts to 20 W in general power supply flyback applications. Thanks to the new approach, the new controller eliminates the need for an auxiliary feedback circuit for constant current regulation, while achieving excellent line and load regulation using a conventional optocoupler and TL431 voltage reference. The NCP1366 operates in a valley-lock quasi-resonant peak current control mode at high loads to provide high energy efficiency. When auxiliary side power starts to disappear, the controller will automatically adjust the duty cycle, then at lower loads, the controller goes into pulse frequency modulation with a fixed peak current through valley switching detection. This technique allows output regulation to be maintained under small dummy loads. Valley lockout in the first 4 valleys prevents valley skipping operation, then valley switching at lower loads provides high energy efficiency.

The FAN3223-25 ​​series of dual 4-A gate drivers provides high peak current pulses with short switching intervals for driving N-channel enhancement mode MOSFETs in low-side switching applications. The driver offers TTL or CMOS 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 to drive one MOSFET. The FAN322X driver integrates the MillerDrive structure for the final output stage. This bipolar MOSFET combination provides high current during the Miller plateau phase of the MOSFET turn-on/turn-off process to minimize switching losses while providing rail-to-rail voltage swing and reverse current capability. The FAN3223 provides two back drivers and the FAN3224 provides two non-back drivers. Each device has dual independent enable pins that default to an on state if left unconnected. In the FAN3225, each channel has two inputs of opposite polarity and can be configured as non-inverting or inverting with selectable enable using the second input. If one or both inputs are left unconnected, internal resistors bias the inputs so that the output pulls low to keep the power MOSFETs off.
