Introduction

FAN1117AD25X is a voltage regulator IC designed for use in low-voltage, high-efficiency switching power supplies. This low-power efficiency regulator can provide cooling of up to 2A of current in a 12 to 15-V DC input voltage range. It is capable of high-current 30A output short-term peak. The device can also be configured for either synchronous or asynchronous Buck or Buck-Boost conversion. Additionally, the FAN1117AD25X is designed for low input-to-output voltage ratios, making it ideal for power supply applications such as USB and adapter chargers.

Application & Working Principle

The FAN1117AD25X voltage regulator is ideal for a variety of power supply designs and applications. It can support both synchronous and asynchronous Buck or Buck-Boost conversion, allowing designers to maximize the efficiency of their device while maintaining a low input/output voltage ratio.In operation, this device is controlled by a P-Channel MOSFET (power transistor) at the output node. The P-channel MOSFET is used in this voltage regulator to reduce the amount of power wasted in the output circuit and to provide a constant output voltage and current. The FAN1117AD25X voltage regulator works by comparing the actual output voltage to an externally programmed reference voltage. Using an internal error amplifier, the regulator then adjusts the buck converter drive duty cycle to compensate for any differences between the two voltages. This ensures a steady output voltage regardless of changes in the input voltage or load current. Finally, the FAN1117AD25X also features various safety features for protection against over-current, over-voltage, and short-circuit, making it suitable for use in low-voltage, high-efficiency switching power supplies.

Conclusion

The FAN1117AD25X voltage regulator is a versatile IC designed for use in low-voltage, high-efficiency switching power supplies. It supports both synchronous and asynchronous buck or buck-boost conversion and offers various safety features for protection against over-current, over-voltage and short-circuit. With its low input/output voltage ratio, this device is ideal for use in power supply designs such as USB and adapter chargers.
