CL1126 is an excellent performance of the primary side feedback controller, which integrates a variety of protection features. CL1126 minimize the number of system components and the use of SOT-23-6L package, which makes the CL1126 better used low-cost design. CL1126 has a low current start function and current sampling LEB. Meanwhile, CL1126 with overvoltage protection function to prevent the circuit from being damaged in exceptional circumstances. Characteristics ◆ ± 5% constant voltage accuracy, ± 5% of the current precision ◆ primary side feedback eliminates the need to reduce costs TL431 and optocoupler ◆ Low start-up current: 1μA (typ) ◆ Low Quiescent Current: 400μA (typ) ◆ Adjustable output constant voltage, constant current and peak current mode control power ◆ ◆ ◆ compensate for transformer inductance tolerances cable drop compensation ◆ Built leading edge blanking circuit (LEB) ◆ ◆-by-cycle current limiting voltage protection (UVLO) ◆ VDD OVP Applications Protection of low-power AC / DC off-line switching power supply is applied: ◆ phone / cordless phone charger digital camera battery charger ◆ ◆ ◆ Small Power Adapter PC / TV auxiliary power ◆ alternative linear power CL1126 uses SOT-23-6L package
