AP3105NV
Overview
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.
- Function Description
- 1 CTRL Pin For some applications, the system requires external programmable protection function. The CTRL pin has two kinds of modes to trigger the protection: high level trigger and low level trigger. The low threshold voltage is 0.5V and high threshold voltage is 2.5V. When the CTRL pin voltage is lower than 0.5V or higher than 2.5V, latch or auto-restart protection will be triggered (different versions of AP3105NX offer different protection combinations, which are shown in Table 2).
