PMIC - Voltage Regulators - DC DC Switching Regulators

The FAN2108MPX is an integrated circuit switch mode DC-DC converter used in step-down and step-up applications. It provides a high power capability with two 5A or two 10A output pins that can both be used together or independently.The FAN2108MPX utilizes a high switching frequency operation of up to 1 MHz, allowing for smaller external components for a wide range of powers. The device works with a minimum input voltage of 3V, and can theoretically output up to 40V required by some high power applications. It also includes advanced features such as integrated power-on sequencing, EMI protection from input to output and comprehensive protection from over-voltage, under-voltage, over-current, over-temperature, power-bypass and brown-out. It can also monitor the temperatures using a sense pin for better reliability and thermal performance.The main application of the FAN2108MPX is in the field of power supply regulation, providing both step-up or step-down voltage regulation to meet the power needs of a wide range of electronic equipment. They are used in a variety of applications such as audio and broadcast equipment, telecommunications equipment, medical instruments, industrial systems and automotive applications.The working principle of the FAN2108MPX is based on the Pulse Width Modulation (PWM) technique, which works by rapidly turning the power switch ON and OFF, where the ratio of ON time to OFF time is determined by the power supply voltage and the output voltage. It uses a low pass filter for the conversion of pulses into an average voltage, and incorporates an integrated high side and low side Switching MOSFETs for controlling the power switch. This allows the device to work with either unipolar or bipolar input voltages, and provides high efficiency over a wide input voltage range.Using the integrated PWM control circuit, the FAN2108MPX can be used on both synchronous and non-synchronous switching systems. The PWM control also provides for accurate and low noise output, as well as low output ripple. The frequency of the output can be adjusted by an on-chip oscillator, or by programming the input cycle time. It also incorporates a programmable soft start circuit, which helps to reduce inrush current during start-up and thus extending the lifetime of the system.To sum up, the FAN2108MPX is a versatile DC-DC switch mode converter that can be used in a variety of applications to provide reliable and efficient power regulation. It is designed to meet the requirements of cost-sensitive and space-constrained applications such as automotive, broadcast and industrial systems. By utilizing advanced features such as PWM control, power-on sequencing and over-temperature protection, it is able to ensure superior performance and added level of protection for a wide range of applications.
