Power IC63513 pin kick function
Power management chip 8 pin description
1, the foot (COMP) is the error amplifier compensation foot. The RC compensation network should be connected between the pin and the inverting input of the error amplifier (VFB) to improve the performance of the error amplifier.
2, the foot (VFB) is the inverting input of the error amplifier. The feedback voltage is fed into the pin and compared with the reference voltage at the in-phase input of the error amplifier to set the error voltage.
3, the foot (ISENSE) is the in-phase input end of the current sampling comparator. The voltage drop at both ends of the current sampling resistor is applied to the pin and compared with the error voltage (maximum 1V) applied to the inverting input of the amplifier to determine the duty cycle of the output drive pulse.
4, foot (RT\/CT) for the external oscillator timing resistance and timing capacitance. The reference resistance is connected between the pin and the reference voltage output pin (VREF), and the reference capacitance is connected between the pin and the ground pin.
