The accuracy of the chip +5.1V reference voltage is 1%. Because the reference voltage is within the input common- mode range of the error amplifier, there is no need for an external resistor. 3525 can work in master- slave mode and can also be synchronized with external clock. The dead time can be adjusted by the resistance between CT and discharge terminal. Other functional circuits inside the chip also include: soft start circuit, turn- off circuit and under- voltage circuit. The output stage of the control chip is a high- power totem- pole output, and its source current and sink current exceed 150mA, which gives a logic level of "NOR" and a low level when it is in the "off" state trait.
