Working principle

The ACT4513YH-T DC-DC switching regulator is an adjustable-voltage regulator module that uses a Pulse width Modulation (PWM) approach to provide high-efficiency voltage and current regulation. The module uses a feedback loop to detect the output voltage, and adjusts the duty cycle of the PWM drive accordingly to maintain the output voltage within a pre-set range. This process is similar to that of a voltage regulator IC.

The module is composed of two major components: a primary control IC, and an optional secondary voltage regulator IC. The primary control IC is a three-terminal device that combines all of the regulating, protection and logic functions in a single IC. The optional regulator IC serves as an additional source of current to the module, reducing the power dissipation of the primary IC in certain applications.

The ACT4513YH-T DC-DC switching regulator module has an adjustable output voltage, a wide input voltage range, and an adjustable switching frequency. It is designed to provide an adjustable output current of up to 2.5A and a wide input voltage range from 5V to 48V. The wide input voltage range enables the module to be used in both AC and DC power systems, making it very suitable for many applications.

The module is also equipped with several protection features, including under-voltage lockout (UVLO), over-current protection (OCP), and short-circuit protection (SCP). These features provide advanced protection for the device and its load from abnormal conditions.

Conclusion

The ACT4513YH-T DC-DC switching regulator is a compact, lightweight, cost-efficient module that is suitable for a wide range of applications. It is capable of providing a stable output voltage and current, and is equipped with several protection features to prevent abnormal conditions. Its wide input voltage range allows the module to be used in both AC and DC power systems, making it very versatile. As such, the ACT4513YH-T DC-DC switching regulator is an ideal choice for a wide variety of applications.
