SD6835 PWM CONTROLLER WITH BUILT-IN HIGH VOLTAGE DIP IC

SD6835 PWM CONTROLLER WITH BUILT-IN HIGH VOLTAGE DIP IC

The SD6835 is current mode PWM controller used for SMPS with built-in high-voltage MOSFET and external sense resistor. It features low standby power and low start current. In standby mode, the circuit enters burst mode to reduce the standby power dissipation. The SD6835 is a current-mode PWM controller designed to drive power MOSFETs in low-power applications. It integrates a variety of features like frequency jittering, overvoltage protection, and low standby power consumption, making it ideal for use in compact and high-efficiency SMPS designs. Built-in peak current compensation circuit makes the limit peak current stable even with different input AC voltage. 

• Lower start-up current (4µA)
  

• Various switching frequency following load for the high efficiency
  

• EMI Frequency jitter for low EMI
  

• Overvoltage, overload and over temperature protections
  

• External peak current sense resistor
  

• Limit output power compensation
