FAN2110MPX Application Field and Working Principle

FAN2110MPX is a cost-effective, low-noise switching regulator from Fairchild Semiconductor. As part of the Field Environment Adaptive Regulator System (FEAR) family, it provides the flexibility and scalability required to meet the needs of a variety of applications. FAN2110MPX is a DC-DC switching regulator, which can be used to convert either a battery or an external AC power supply into a regulated voltage.

FAN2110MPX is designed to provide a wide range of applications, ranging from notebook and desktop computer systems to automotive and industrial applications. It is also well suited for Point-of-Load (POL) applications, where it can be used to provide an isolated, regulated power supply when required. FAN2110MPX also offers selectable current limit and soft-start features for system protection.

FAN2110MPX has a wide input voltage range of 3V-35V, providing it with the versatility to be used in a variety of different applications. The output voltage can be adjusted from 0.8V to 12V, with a maximum output current of 2A. The converter also has a switchable output frequency of 300kHz, 600kHz and 1.2MHz. The part includes programmable features such as overcurrent protection, short-circuit protection, overvoltage protection, and power-good indicator.

FAN2110MPX has an on-chip power MOSFET switch, allowing it to be used as a step-down converter or as a linear regulator. In step-down mode, the converter steps the input voltage down to a lower output voltage. In linear regulator mode, the input voltage is regulated to a constant output voltage. The switching frequency, ratio of duty cycle, switch voltage, and current are all programmable.

The FAN2110MPX DC-DC switching regulator features a constant frequency current mode control for fast transient response and high output accuracy. It also offers an adjustable 1A internal current limit, with a fixed output current of 2A. The design also includes selectable forced PWM or auto-low-noise operation, allowing the user to fine-tune the regulation according to application requirements.

FAN2110MPX is available in a 4x4 mm QFN package and is RoHS compliant. It has an operating temperature range of -40°C to +125°C, making it suitable for a variety of applications and environments. The device also features protection against ESD, EFT, reverse current, overvoltage, and undervoltage.

FAN2110MPX DC-DC switching regulators are a cost-effective solution for a variety of applications. It combines the advantages of both linear and switching regulator technologies, providing high efficiency, fast transient response and high output accuracy. The parts are also highly configurable, with a wide range of features available.
