SG1526J-883B Application Field and Working Principle

SG1526J-883B is a high performance DC DC switching controller manufactured by Microsemi, a leading provider of power management solutions. It is specifically designed to be an all-in-one solution for wide range of portable applications in mobile phones and other portable devices. It operates in the range of 3.3V to 5.5V and offers full protection against overtemperature, overcurrent and undervoltage conditions.

The design of SG1526J-883B enables the user to select the operating frequency and other parameters, making it ideal for a variety of applications. It is designed to generate both synchronous buck and non-synchronous buck voltage. Its primary application field is the generation of step down voltage in power supplies, but it can also be used for boost, flyback, buck-boost and positive/negative voltage transfer.

The SG1526J-883B works by using an internal oscillator and pulse width modulation (PWM) for regulating the output voltage. This switching is done using an external MOSFET. By using PWM, the SG1526J-883B can achieve efficiencies as high as 95%. It also supports low standby power consumption of <10uA, and wide input voltage range that covers almost all the popular battery cells.

The design of the SG1526J-883B also features a precision reference voltage accuracy of ±2%. This enables it to deliver high quality and reliable operating performance in power saving applications. It also features low offset and low jitter voltage mode switching with hysteretic and auto-skip modes. With its built-in oscillator, it can also provide frequencies as high as 1.5MHz.

The SG1526J-883B is an ideal solution for low-voltage systems, including mobile phones, tablet computers, and other mobile applications. Due to its wide range of features and characteristics, the industry leading company Microsemi has designated it as the top choice for many of its customers for providing DC DC switching control. It is also one of the most respected solutions for power control applications in all kinds of mobile devices.
