AP1507-50D5L-U

The AP1507-50D5L-U is a switching voltage regulator from the DC-DC Converters product family from Advanced Power. This regulator is part of the Buck-Boost category of regulator, meaning it is able to consistently output either an increased, equal, or decreased voltage depending on the application.

Application Field

The AP1507-50D5L-U can be applied to a variety of circuits, in particular those that require the circuit components to operate at consistent, regulated voltages. This regulator is able to accurately regulate the output voltage for a wide range of applications.

Many consumer electronic products require small, self-contained power supplies that are easy to integrate into the product’s design. The AP1507-50D5L-U is an ideal choice for such products, as it is small, low cost, and able to provide consistent, regulated power.

The AP1507-50D5L-U is also an excellent choice for situations where the power supply needs to have a wide input voltage range. This regulator can handle input voltages from 5V to 36V, which makes it useful for products that require power from a battery or another source.

Working Principle

The AP1507-50D5L-U is a buck-boost regulator, meaning it is able to both increase and decrease the output voltage. It achieves this by making use of two switches that are connected in series in an H-bridge configuration.

When the input voltage is lower than the desired output voltage, the two switches are used to alternately charge and discharge an inductor, which stores energy and increases the output voltage. When the voltage is higher than the desired output voltage, the switches are used to alternately discharge and charge the inductor, which releases energy and decreases the output voltage.

The AP1507-50D5L-U also uses a feedback loop to compare the output voltage with the desired voltage. Whenever the output voltage deviates from the desired voltage, the feedback loop modifies the duty cycle of the switches in order to return it to the desired value.

The AP1507-50D5L-U also uses its built-in protection functions to protect both the device and the connected components. It has a built-in current-limiting protection that prevents current spikes, as well as a thermal shut-down protection that prevents overheating.

Conclusion

The AP1507-50D5L-U is a versatile switching voltage regulator, able to accurately regulate both high and low voltages. Its small size and low cost make it an excellent choice for products requiring a small, self-contained power supply. It also provides excellent over-current and over-voltage protection, making it a safe, reliable choice for most applications.
