Application Note 1096 High Voltage Green Mode PWM Controller AP3105NA/NV/NL/NR Prepared by Wu Qikun System Engineering Dept.
1.
Introduction The AP3105NX is a low start-up current, current mode PWM controller with green-mode power-saving operation.
Different from AP3103, AP3105NX’s PWM switching frequency at normal operation is fixed at 65kHz dithering with a narrow range.
The difference between AP3103 and AP3105NX is shown in Table 1.
The dithering of frequency will improve EMI feature.
When the load decreases, the frequency will reduce and when at a very low load, the IC will enter the “burst mode” to minimize switching loss.
A minimum 20kHz frequency switching is to avoid the audible no...
