U3848A current source PWM controller:

U3848A is UTC for meeting the new "" European energy star" and roll out environmental protection power IC, U3848A start voltage and off than the low voltage LD7575, starting current is also low, start low consumption. All have pressure, flow, short circuit protection function, can be adjusted, static frequency power consumption to meet all the new European standards. Widely used in switching power supply, charger, adapter, LCD, TV display power supply.

1. To circulate on the market at present the power IC comparison of the:
