MP2908AGL-P Application Field and Working Principle

The MP2908AGL-P is an integrated power switch IC with power management and current balancing capabilities. It is an integrated, highly integrated, and highly reliable switching regulator ideal for applications such as MP3 players, portable electronic devices and power supplies. This multi-channel, DC–DC inductive switching regulator provides excellent power performance and maximum efficiency in versatile and compact designs.

The MP2908AGL-P belongs to a class of PMIC (power management ICs) known as DC–DC switching regulator. This type of regulators, also called buck converters, are use in many different circuits and the main purpose is to regulate the output or main voltage of a power supply. This type of regulator typically consists of a control circuit, switching circuit, thermal protection, feedback circuit and an energy storage device.

The MP2908AGL-P is based on advanced CMOS technology, featuring high efficiency, low noise, and stable and fast transient response. Its design can be used to take an input voltage of up to 6.3V and generate an output voltage of up to 20V. Its switching frequency can be set in a wide range from 16kHz to 200kHz with the integrated frequency adjustment PFM (pulse-frequency modulation).

The MP2908AGL-P is designed for easy integration in high performance and cost sensitive applications. It has a wide operating temperature range from -25℃～85℃, providing high efficiency and low on-resistance for high current surge applications.

The ICs also feature two DMOS channels for multi-channel multiplexing operation, allowing for dynamic power management and possibility of current-balancing.

The MP2908AGL-P also has several built-in features such as soft-start, frequency jitter, temperature compensation, current limiting, and built-in self-test features.

In summary, the MP2908AGL-P is a high-efficiency DC–DC switching regulator, suited for various power management applications such as MP3 players, portable electronic devices and power supplies, providing high efficiency, low noise and a wide operating temperature range.
