Gate Output Voltage Clamp

ZSLS7031 provides the voltage clamp for the GATE output. When the voltage at VCC is smaller than the VGATEclp

threshold (see specification 1.3.3), the output high voltage of the GATE output is approximately VCC. When the

voltage of VCC is greater than the VGATEclp threshold, the output high voltage of GATE is limited to the VGATEclp

threshold.

2.5

VSINE Detection Network and Active PFC

The voltage VSINE at the VSINE pin is used to control the waveform of the input current to ensure that it follows the

input voltage waveform, VBULK, to achieve a high power factor (PF) and low total harmonic distortion (THD) perfor-

mance, as demonstrated in Figure 2.3.
