⚡ SD6835 Current Mode PWM+PFM Controller with Built-in HV MOSFET – Now in Stock
We are pleased to announce the availability of the SD6835 current mode PWM+PFM controller IC from Silan Semiconductor. This highly integrated power management IC features a built-in high-voltage MOSFET and is designed for efficient, reliable switched-mode power supply (SMPS) applications.
The SD6835 delivers up to 26W of output power with less than 0.3W standby power, making it ideal for energy-efficient adapter and charger designs.
⚡ What is the SD6835?
The SD6835 is a current mode PWM+PFM controller IC with a built-in high-voltage MOSFET. It is designed for use in offline flyback power supplies, providing efficient power conversion with minimal external components. The IC automatically adjusts its switching frequency (25KHz to 67KHz) based on load conditions, optimizing efficiency across the entire operating range.
With features like burst mode operation, frequency jitter for low EMI, and comprehensive protection (overvoltage, overload, overtemperature, and undervoltage lockout), the SD6835 is a robust and reliable solution for modern power supply designs.
