CURRENT MODE PWM+PFM CONTROLLER WITH BUILT-IN HIGH
VOLTAGE MOSFET
DESCRIPTION
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.
Built-in peak current compensation circuit makes the limit peak
current stable even with different input AC voltage. Built-in limit
output power compensation circuit to balance the limit output power
under different AC voltage inputs. Built-in slope compensation
circuit to adapt to more transformer applications. Maximum peak
current compensation during power-on reduces pressure on
transformer to avoid saturation, the peak current compensation will
decrease for balance after power-on. Limit output current can be APPLICATIONS
adjusted through the resistor connected to CS.
It integrates various protections such as undervoltage lockout,
SMPS
overvoltage protection, overload protection, leading edge blanking
and thermal shutdown. The circuit will restart until normal if
protection occurs.
FEATURES
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
Slope compensation
Undervoltage lockout
Built-in high voltage MOSFET
Auto restart mode
Peak current compensation
Maximum peak current compensation for initialization to
realize the soft start function.
