CSC8513 (PSR built-in MOS drive 3~5W, isolated flyback, low cost).rar

General Description of CSC8513
 The CSC8513 is a high precision primary side feedback constant current LED driver chip. The chip operates in the DCM mode, suitable for 85VAC~265VAC full range of input voltage,power below 5W flyback isolated LED constant current power supply. The internal circuitintegrated 650V high voltage power MOS tube, the primary side feedback mode, withoutsecondary feedback loop, without compensating circuit. The CS average current detection technology, very low chip working current, further reducing peripheral components, greatly saving the cost of the system.
The CSC8513 design of the current sampling circuit of high precision, so that the LED output current accuracy is ± 5%. Chip with constant current control mode characteristic, can achieveexcellent linear adjustment rate. The unique LED open / short circuit protection, CS resistanceshort-circuit protection, under voltage protection, over temperature protection chip multiple protection function to increase the reliability of the circuit. This circuit uses the SOP-8package.
