40、mbol I/O Description CAO O Output of the wide bandwidth current amplifier and one of the inputs to the pulse width modulator (PWM) duty-cycle comparator. The output signal generated by this amplifier commands the PWM to force the correct input current . The output can swing from 0.1 V to 7.5 V CT I
41、Capacitor from CT to GND sets the PWM oscillator frequency. ENA I A nominal voltage above 2.65 V on this pin allows the device to begin operating. Once operating, the device shuts off if this pin goes below 2.15 V nominal. GND - All bypass and timing capacitors connected to GND should have leads as
42、short and direct as possible. All voltages are measured with respect to GND. GTDRV O Output of the PWM is a 1.5 A peak totem pole MOSFET gate driver on GTDRV. This output is internally clamped to 15 V so that the device can be operated with VCCas high as 35 V. Use a series gate resistor of at least
43、5 to prevent interaction between the gate impedance and the GTDRV output driver that might cause the GTDRV output to overshoot excessively. Some overshoot of the GTDRV output is always expected when driving a capacitive load. IAC I Current input to the multiplier, proportional to the instantaneous l
44、ine voltage. This input to the analog multiplier is a current. The multiplier is tailored for low distortion from this current input (IAC) to MOUT, so this is the only multiplier input that should be used for sensing instantaneous line voltage. The nominal voltage on ac is 6 V, so in addition to a r
45、esistor from IAC to rectified 60 Hz, connect a resistor from IAC to VREF. If the resistor to VREF is one fourth of the value of the resistor to the rectifier, then the 6 V offset is cancelled, and the line current has minimal cross over distortion. ISENSE I Switch current sensing input. This is the
46、inverting input to the current amplifier. This input and the non-inverting input MOUT remain functional down to and below GND. Care should be taken to avoid taking these inputs below -0.5 V, because they are protected with diodes to GND. MOUT I/O Multiplier output and current sense plus. The output
47、of the analog multiplier and the non-inverting input of the current amplifier are connected together at MOUT. The cautions about taking ISENSE below -0.5 V also apply to MOUT. As the multiplier output is a current, this is a high impedance input similar to ISENSE, so the current amplifier can be configured as a differential amplifier to reject GND noise. PKLMT I Peak limit. The threshold for PKLMT is 0 V. Connect this input to the negative voltage on the current sense resistor. Use a resisto
