S-8520A26MC-AVLT2G Application Field and Working Principle

The S-8520A26MC-AVLT2G is a DC-DC switching controller for portable devices requiring high efficiency, low power consumption and noise reduction. This device can be found in many applications such as smartphones, laptops, game consoles and industrial systems, among others. 

The S-8520A26MC-AVLT2G implements an open loop architecture that is, the output voltage of the switching regulator is not compared with a reference voltage. The controller automatically compensates for component variation and power supply variations with its high frequency predictive voltage feedback loop. This regulator uses an input voltage range of 2.5V to 5.5V and provides an adjustable output voltage range between 1.1V to 4.5V. Besides, it supports four output current settings, which are between 10mA to 4A for each output. The output ripple voltage of the S-8520A26MC-AVLT2G is extremely low and can be of approximately 20mV (100mV typical).

The S-8520A26MC-AVLT2G also provides several features such as over-current protection, over-temperature protection, under-voltage lockout, over-voltage protection, etc. All these features guarantees a higher power output efficiency and a better protection to the controller itself. The device operates under a wide temperature range (from -40°C to 125°C) and supports light load detect mode that ensures a prolongs battery life.

In conclusion, the S-8520A26MC-AVLT2G is a perfect choice to use on portable devices that require high efficiency and low heat generation. Its easy control and its very low start-up time make this device suitable for any application requiring a quick response time.
