The FAN2558MP15X is a step-up converter made by Vishay Semiconductor that converts a low voltage DC input into a higher-voltage DC output. This device is a perfect fit for applications where low start-up voltage and low quiescent current are the most essential requirements. The FAN2558MP15X operates with high efficiency and wide range of input/output voltages. The device uses an energy storage inductor and a similarly high-efficiency MOSFET to switch the output voltage up or down.

FAN2558MP15X is available in three versions: MP15XS-LF, MP15X and MP15XR-LF. The MP15XS-LF is the simplest version, which offers a single voltage step-up configuration and works with a maximum input voltage of 4.2V and a typical output voltage of 15V. The MP15X offers two configurations: single voltage step-up and adjustable buck-boost, with a maximum input voltage of 6V and output voltage up to 16V. Finally, the MP15XR-LF has the same functions as the MP15X and it offers an adjustable output voltage with a range of 8-16V.

The FAN2558MP15X integrates a wide range of features that make it very suitable for numerous applications. The device has a maximum output current of 1.5A and it is capable of providing an output power up to 15W when used in step-up mode. This makes the FAN2558MP15X an ideal choice for applications such as low-power power inverters, DC-DC converters for automotive, battery-powered devices, and solar energy systems. Furthermore, the device is also capable of operating in buck-boost mode, which makes it suitable for applications requiring a wide input voltage range.

The FAN2558MP15X operates in a fixed frequency PWM control mode and it uses internal current sensing circuitry to detect and limit the output current. The device also features under-voltage lockout (UVLO) which prevents the device from working if the input voltage is too low. In addition, the device also includes short-circuit protection, thermal protection and reverse polarity protection to ensure safe operation and prevent potential damages to the device.

The switching frequency of the FAN2558MP15X can be adjusted with an external resistor and its standby current consumption is fairly low, with a maximum of 30uA. This makes the device optimal for applications where the power consumption needs to kept low while the output voltage is powered by a very low voltage. Furthermore, the device has low start-up and shutdown times which makes it suitable for applications where the output voltage needs to be adjusted quickly and smoothly.

Overall, the FAN2558MP15X is a highly integrated DC/DC converter that provides multiple configurations, high efficiency, and a wide range of input/output voltages for a wide range of applications. Its features make it ideal for low-power applications such as automotive, battery-powered devices, and solar energy systems. Besides, its low standby current consumption, fast start-up and shutdown times make it suitable for applications that require quick and smooth voltage adjustments.
