Voltage regulators are widely used in electronic applications to protect electronic devices from power fluctuations and maintain an optimal working voltage. The AP65402SP-13 is a DC DC switching regulator perfect for applications that require high efficiency, hot start-up protection, and sync frequency of up to 1MHz. It is a popular choice for use in a wide range of gadgets and digital appliances.

Electrical Characteristics

The AP65402SP-13 is a low-voltage switching regulator that comes in a compact 10-pin SOIC package. It features a wide input voltage range of 4.5V to 40V and has an operating temperature range from -40°C to +85°C. Each of the two outputs can provide up to 2A peak current, which ensures efficient operation. This regulator provides overvoltage, overcurrent protection, and thermal shutdown for higher reliability and is also compatible with energy-saving Eco-mode.

Application Field

Due to its high efficiency, excellent load regulation, and small size, the AP65402SP-13 is ideal for a variety of commercial, industrial, and consumer applications. It is particularly suitable for use in devices that require hot start-up protection and high accuracy. These could include digital cameras, LCD monitors, or industrial equipment, among others.

Working Principle

The AP65402SP-13 is a DC DC synchronous switching regulator that utilizes pulse width modulation (PWM) to provide highly efficient voltage and current conversion. When a "High" signal is applied, the regulator goes into the PWM mode and the cascode circuit begins to provide stable current flow against load changes. The output voltage can be adjusted by connecting a voltage divider between the pins of the regulation voltage output and ground.

The AP65402SP-13 also assists in improving power conversion efficiency by using noise control algorithms, which are activated by adjusting the frequency control voltage of the frequency oscillator. A higher level of noise control can be achieved at a lower frequency range (range from 100 kHz to 1MHz). It also helps to reduce ripples and drops in output voltage.

Conclusion

To summarize, the AP65402SP-13 is a highly versatile voltage regulator with excellent performance and great features. Its wide input voltage range, small size, high efficiency, and hot start-up protection make it ideal for a wide range of applications, including commercial and industrial applications. Additionally, its adjustable voltage and sync frequency also help improve its power conversion efficiency.
