新型电源（国外英文资料） 17 kinds of new color circuit switching power source integrated circuit data 1, KA3S0680RFB KA3S0880RFB KA3S0680RFB KA3S0880RFB FAIRCHILD Japanese company is the production of switch power supply circuit, the built-in power MOSFET and control circuit, its internal has overheating protection circuit, over current, over voltage, low voltage limiter circuit, high voltage sensing circuit, etc. The internal circuitry of the KA3S0680RFB and KA3S0880RFB is basically the same as the internal circuit of the high working frequency, high efficiency, and stable work, except the output power is different (KA3S0680RFB power is 150W; KA3S0880RFB power is 190W). It is used in the new type of color TV of haixin DP2999. The KA3S0680RFB KA3S0880RFB is shown in table 1 for the function and maintenance data. The pin function haixin DP2999 is high in beauty Resistance to ground voltage () to (K Ω) of voltage (V) to ground resistance Ω (K) The red pencil test will be used for the red pencil test The output of a DRA IN a built-in power switch tube is 300 5.7 500, 570, 280, 3.8 infinity GND ground zero zero zero zero zero zero The Vcc power source is 20, 5, 500, 16, 15, 3.3, and infinity The number of responses was 1.8, 8, 200, 200, 0.2, 5.7, 200 SYNC SYNC entered 7.1 7.5 31 6.3 3.8 5.4 30 2, A5Q1265RF A5Q1265RF FAIRCHILD Japanese company is the production of FPS type switching power supply control circuit, a built-in type has a strong withstand voltage of 650 v current field effect tube and power control circuit, and is equipped with over-current, over-voltage, overheating protection circuit (when the chips surface temperature over 150 ℃, automatically cut off the output; when the voltage of the power supply side (3) feet higher than 11 v, 24 v or lower chip stop working). It is being used in the new color TV set of the haier UOC chip. The A5Q1265RF pins function and maintenance data are shown in table 2 The pins function haier UOC Resistance to ground voltage () to (K Ω) The
