AP3105L - High Voltage Green Mode PWM Controller

Download the AP3105L datasheet PDF. This datasheet also covers the AP3105 variant, as both devices belong to the same high voltage green mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

Description

2.1 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 is 2.5V.

Features

  • which include cycle-by-cycle current limit (OCP), fast OCP (FOCP), VCC over voltage protection, OTP, OLP protection. The “CTRL” pin is designed for customers to add external protection functions such as OVP and OTP. The AP3105 is specially designed for off-line AC-DC power supply, such as LCD monitors, notebook adapter and battery charger.

Application Note 1062 High Voltage Green Mode PWM Controller AP3105 Prepared by Wu Qikun System Engineering Dept. 1. Introduction The AP3105 is a low start-up current, current mode PWM controller with green-mode power-saving operation. Different from AP3103, AP3105 PWM switching frequency at normal operation is fixed at 65kHz dithering with a narrow range. The difference between AP3103/AP3105 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 noise as well as reducing the standby loss.
