Application Fields of ALD114835PCL

ALD114835PCL is designed for use in a variety of power management applications. As a constant current source array transformer, it is usually applied to applications with constant current demands, such as:

• Switching Mode Power Supplies (SMPS)
• DC-DC converters
• Battery chargers
• LED constant current drivers

ALD114835PCL also offers an ideal solution for sensing loadcurrent in light load applications, such as notebook computers and standby power supplies.

Working Principle of ALD114835PCL

The device has two main components: the power supply and a power MOSFET array. The power MOSFET array is the key component of the ALD114835PCL and consists of two sections: the control electronics and the output transistor array. The control electronics section is responsible for monitoring the input voltage, controlling the output voltage and current of the device, and providing over-current protection.

The output transistor array is responsible for providing current-limiting of the device and providing a stable output voltage across the load. The output transistor array is protected against short-circuits and over-current by the control electronics, which reduces the risk of any unexpected damage to the device. Furthermore, the device offers a wide temperature range operation of up to -40°C to +125°C allowing for reliable operation in extreme temperatures.

The device requires only a single external resistor to set the output current, significantly simplifying its design and removing the need for any complex circuit topologies. Furthermore, its wide input voltage range of +2.7V to +18V coupled with its low quiescent current of approximately 2.5μA, makes the ALD114835PCL highly efficient and cost effective.

Conclusion

The ALD114835PCL is a highly efficient and cost-effective array transformer designed for use in power management applications such as SMPS, DC-DC converters, battery chargers, LED constant current drivers, and others. Its features and components make it easy to design and use, while its wide temperature range allows reliable operation even in extreme temperatures.
