Adjustable Switching Frequency (200kHz to 1MHz): This feature allows designers to optimize the switching frequency for specific applications, balancing efficiency and electromagnetic interference (EMI). Higher frequencies enable smaller passive components, reducing the overall size of the power supply, while lower frequencies improve efficiency in high-power applications.
Synchronization to External Clock: By synchronizing the PWM controller to an external clock, this feature minimizes noise and interference in systems with multiple power supplies. This is particularly beneficial in telecom and network systems where precise timing and reduced EMI are critical.
Programmable Volt-Second Limiting: This feature simplifies transformer design by allowing designers to set a constant maximum volt-second value. It ensures consistent transformer operation across varying input voltages, enhancing reliability and reducing design complexity in isolated DC-to-DC converters.
Programmable Hiccup/Skip Cycles or Latch-Mode Protection: This feature provides flexible fault management, allowing the controller to either enter a low-power hiccup mode or latch off during overcurrent or overvoltage conditions. It improves system reliability and protects sensitive components in high-performance offline AC/DC converters.
Internal and External Gate Driver Options: The inclusion of both internal and external gate drivers offers versatility for low-power and high-power applications. The internal driver reduces component count and cost for low-power designs, while the external driver supports higher power levels, making the controller suitable for a wide range of use cases.
