AP1501-50K5G-13

AP1501-50K5G-13 is a part of a family of monolithic DC-to-DC step-down switching regulator controllers. It operates with an input voltage range of 4.5V up to 20V and provides a highly inductive step-down conversion of up to 50W, with an output voltage range of 0.8V to 8V. This family features integrated circuits which can maintain a constant output voltage while regulating both input voltage and load conditions.

Application Field

AP1501-50K5G-13 are primarily used in voltage conversion applications where the input voltage is higher than the regulated output voltage. The output voltage regulation can be adjusted via an external preset, allowing the circuit to be used in power supplies, battery management, automotive systems, low-voltage audio, and portable systems.

AP1501-50K5G-13 can also be used in wide range of applications, such as consumer electronics, battery backups, motor control and embedded systems. The low power requirements of this family make it well-suited for applications which require extremely low power dissipation. This family of controllers is also highly reliable and is designed for a long life cycles.

Working Principle

The AP1501-50K5G-13 operates by using a step-down converter configuration. This configuration consists of a switching transistor, an inductor, and two capacitors connected in series. The inductor stores energy in its magnetic field, while the capacitors provide a reservoir of energy and can also be used to filter noise.

The voltage at the output is regulated by the controller. When the voltage drops below a certain level, the controller detects this and switches on the switching transistor. This feeds power to the output through the inductor. When the output voltage reaches its predetermined level, the transistor is switched off and the inductor stops supplying power.

The AP1501-50K5G-13 can also fulfil unique application requirements with its built-in current limiting feature. This feature is used to protect the circuit from excessive current during any fault condition, providing further assurance of system reliability.

Conclusion

In summary, AP1501-50K5G-13 is a highly reliable and efficient DC-to-DC step-down converter controller family which operates with an input voltage range of 4.5V up to 20V. It is ideal for wide-range of applications such as consumer electronics, battery backups, motor control, embedded systems and automotive systems. It also has a built-in current limiting feature to prevent any faults during operation. The family is also highly reliable and is designed for a long life cycles.
