SD6835 PWM PFM Power Management IC

• SD6835 is current mode PWM+PFM 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 switch frequency is 25~67KHz decided by the load with jitter frequency for low EMI.
• Part Number: SD6835  6835
• Maker: Silan Microelectronics
• Energy Star 2.0 standard
• 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
