AC-DC desktop, wall adapters are mainly used to convert AC power supply to different types of DC power supply. IPD5019-760S is a common type of AC-DC adapter, which supports various kinds of input line and output voltage. In this paper, we will introduce the application field and working principle of IPD5019-760S.

Specifically, IPD5019-760S is designed to work for laptop computers, digital products, LED display products, wireless broadcasting & receiving equipment, telecommunication products, etc. Besides, the output voltage range of IPD5019-760S is 6~24 V, with rated output voltage of 7.6V and output current of 1A. There are also optional LED indicators for the device. Furthermore, the IPD5019-760S also supports tiny size and low noise, with dimension of 67.4x47.3x27mm and no-load power consumption of ≤0.3W.

Compared with other products, IPD5019-760S has higher efficiency. Its full load efficiency is up to 80%, while the output voltage accuracy is 6%, and the temperature coefficient is ±0.02%. Moreover, IPD5019-760S uses up-to-date electric components such as PWM control IC, SMD inductor, and electrolytic capacitor, which make it more reliable. Besides, IPD5019-760S requires minimum of input ripple current, which is lower than 150mV. In addition, the product meets safety approval of UL/EN60950/IEC60950-1.

The working principle of IPD5019-760S is quite simple. It works in a closed-loop control, including input rectifier, PWM control IC (TL494), SMD transformer, output rectifier and output capacitor. It is noted that the main function of the PWM control IC (TL494) is to adjust the on-time of the converter according to the load. And the SMD transformer makes sure that the power supply is isolated from the ground.

To conclude, IPD5019-760S provides good performance in terms of efficiency, accuracy, size, etc. It is ideal for small devices, such as laptop computers, digital products and LED display products, etc. Besides, its working principle is relatively simple. In a word, IPD5019-760S can be used as a great replacement of bulky AC to DC wall adapter.
