S-882155AMH-M3ETFG is a DC DC switching regulator, a type of Switching Voltage Regulator (also called a DC to DC converter or buck-boost converter) that is part of Power Management IC (PMIC) family. It has been developed by Eiger Mobility and is a “dual” device, meaning it can regulate two separate power sources. It can be used to regulate input from a variety of sources, including batteries, solar panels, and AC power outlets. In addition, it can also be used to regulate two different voltages – either low voltage sources such as Li-ion batteries, or high voltage sources such as high electricity grids.

The S-882155AMH-M3ETFG is a full-featured buck-boost converter with wide input voltage range and up to 3A of load current. It offers many features, such as automatic input voltage recognition, low-ripple switching, programmable voltage selection and thermal protection. These features make the S-882155AMH-M3ETFG suitable for a variety of applications, such as battery charging and power supply design. It can be used to provide regulated DC output voltage from an unregulated AC or DC input voltage source.

As a buck-boost converter, the S-882155AMH-M3ETFG works by converting a given input voltage to a desired output voltage. This is achieved by using a high-frequency oscillator to switch an inductor, diode and switch in a fixed switching cycle. The amplifier is operated in peak current mode, where the inductor current is regulated to a peak current, and different voltage outputs are obtained by varying the cycle duty ratio (the on/off ratio of the switching cycle). The circuit has the capability to automatically detect the input voltage and adjust the output voltage accordingly. The S-882155AMH-M3ETFG is rated for up to 300V of input voltage, and up to 3A of output current.

The S-882155AMH-M3ETFG also provides many desirable features and protections, making it suitable for automotive and industrial applications. It offers thermal protection to detect over-temperature conditions, under-voltage lockout (UVLO) and over-voltage lockout (OVLO) to protect the circuitry, cycle-by-cycle current limiting to prevent current overloads, and internal soft-start to reduce inrush currents. Its high efficiency and fast transient response make it an ideal choice for battery charging applications.

In summary, the S-882155AMH-M3ETFG is a high-performance DC to DC converter designed to provide regulated DC power from unregulated AC or DC sources. It has wide input voltage range and up to 3A of load current, and offers many features such as thermal protection, under-voltage lockout, over-voltage lockout, and cycle-by-cycle current limiting. It is suitable for a variety of applications, such as battery charging and power supply design, and is an ideal choice for automotive and industrial applications.
