The FAN2504S25X is a PWM step-down voltage regulator specifically designed for high-efficiency, cost-effective applications. Its features include, but are not limited to, an adjustable output voltage, wide input voltage range, ultra-low quiescent current, and a high switching frequency, making it an optimal choice for high-efficiency, low-power applications. Additionally, the FAN2504S25X offers user-programmable voltage regulation, current-limiting protection, short-circuit protection, and thermal protection, minimizing the need for a separate protection circuit.

The FAN2504S25X belongs to the PMIC - Voltage Regulators - Linear device family, meaning that it uses an inductor voltage and current waveforms to create a linear transfer function for the output voltage. In general, the behavior of the regulator can be divided into two stages, controlling the on and off times of the regulating components. The first stage is the PWM control stage, in which the on and off times of the regulating components are continuously adjusted based on the output voltage. This dynamic adjustment allows the regulator to adjust the inductor current and control the output voltage. The second stage is the linear control stage, which fine-tunes the output voltage based on the feedback signal.

In terms of its functionality, the FAN2504S25X can be used for a wide range of applications. It is suitable for low-power DC-DC converters, battery chargers, battery charger adapters, and other applications that require a stable, low-noise output voltage. Moreover, it can be used as a secondary linear regulator or as a primary switching regulator. Additionally, the FAN2504S25X can be paired with external components such as capacitors, inductors, and transformers to create complex voltage regulation schemes.

The FAN2504S25X operates with an input voltage range of 4.5V to 32V, with an adjustable output voltage range of 0.8V to 5.5V. The device offers current-limiting protection and over-temperature protection, as well as soft-start and power-good signal options. Furthermore, the FAN2504S25X has a low quiescent current of 4μA, making it suitable for energy-sensitive applications. In addition, the device has a switching frequency of 2.25MHz, allowing for a small inductor size for the external circuit.

The FAN2504S25X is a highly efficient and cost-effective PWM step-down voltage regulator. It is suitable for a wide array of applications, from low-power DC-DC converters to battery chargers. With its low quiescent current, adjustable output voltage range, current-limiting and over-temperature protection features, the device is an optimal choice for high-efficiency, low-power applications.
