CL1105 is an excellent performance of the primary side feedback controller, the internal integration of 650V high voltage power transistor, which integrates several protection features. CL1105 minimize the number of system components and uses SOP8 / DIP8 package, which makes the CL1105 better applied to low-cost design. CL1105 has a low current start, current sampling LEB and internal slope compensation. Meanwhile, CL1105 with overvoltage protection function to prevent the circuit from being damaged in exceptional circumstances. Characteristics ◆ ± 3% constant accuracy, ± 3% current precision primary side feedback eliminates ◆ TL431 and optocoupler to reduce costs ◆ Low start-up current: 5μA (typ) ◆ Low operating current: 2mA (typ) ◆ Adjustable output constant voltage, constant current and peak current mode control power ◆ ◆ ◆ compensate for transformer inductance tolerances cable drop compensation ◆ Built-in frequency jitter technology to improve EMI ◆ Built-in soft-start function ◆ Built-edge blanking circuit (LEB) ◆ by-cycle current limit ◆ undervoltage lockout (UVLO) ◆ VDD OVP protection ◆ VDD voltage clamp function ◆ Built-650V high voltage power MOSFET Applications ◆ phone / cordless phone charger digital camera battery charger ◆ ◆ ◆ Small Power Adapter PC / TV auxiliary power ◆ replace linear power CL1105 uses SOP8 / DIP8 package
