The FAN53526UC106X is a DC/DC switching regulator specifically designed for NanoPower applications. It is a versatile, low-cost, and low-power solution that offers both voltage regulation and load current optimization. The FAN53526UC106X can be used in a variety of applications such as digital power supplies, battery management systems, automotive applications, and more. This article will discuss the application field and working principle of the FAN53526UC106X.
The FAN53526UC106X is designed with a wide input voltage range from 2.5V to 18V, making it ideal for most battery-powered applications. The device is a non-synchronous buck step-down converter and provides a continuous output current of up to 250mA while maintaining a tight output voltage regulation. It also offers a wide range of adjustable output voltages, allowing the user to select the desired voltage output within the range of 0.9V to 5.5V. With a built-in load current monitor, the FAN53526UC106X offers close-loop control of the output current to ensure that the output current remains within the specified target current. The device also includes a power-on reset to ensure that the output voltage is regulated at the programmed value.
The FAN53526UC106X utilizes an on-chip low-threshold voltage (Vth) MOSFET for enhanced efficiency and low output voltage ripple. It also features an integrated high-side current sense resistor for enhanced current sensing accuracy. The device is available in a small 10-pin SOT-23 package, allowing for easy integration into space-constrained applications. The device also features impressive efficiency levels, ranging up to 95%, making it an attractive choice for low-power designs.
The FAN53526UC106X’s working principle is based on the properties of a buck converter, which uses an inductor and a switch to reduce the input voltage to a lower output voltage. The device operates in two different modes — an on mode and a sleep mode — which are activated depending on the load current level. In the on mode, the device switches the internal MOSFET periodically, allowing inrush current to flow through the inductor to the load while maintaining a predetermined output voltage. During the on mode, the FAN53526UC106X’s output voltage is regulated by varying the duty-cycle at which the MOSFET is switched on and off.
When the load current drops below a certain threshold, the device enters a sleep mode. In the sleep mode, the device stops switching, resulting in reduced power consumption and improved efficiency. The FAN53526UC106X also features built-in protection against common problems, such as over-temperature, over-current, and output over-voltage. The device can also be disabled via a logic pin to prevent unexpected operation.
The FAN53526UC106X is a low-cost, low-power solution that offers a versatile and efficient DC/DC switching regulation solution for long battery lifetimes. It has a wide input voltage range and adjustable output voltage, allowing for a variety of applications. It also has impressive efficiency levels, ranging up to 95%, making it an ideal choice for low-power designs. The device is available in a small 10-pin SOT-23 package, making it easily integrated into space-constrained applications. Finally, its flexible load current optimization and built-in protection features make it an ideal choice for various battery powered applications.
