AP7343D-23FS4-7B

AP7343D-23FS4-7B, classified as a PMIC -- Voltage Regulators -- Linear device, is primarily used for heavy-duty industrial applications, providing improved system voltage regulation. The AP7343D-23FS4-7B is a switching type linear regulator featuring adjustable current limit and low quiescent current operations. This device is designed to provide superior performance, stability, and efficiency in noisy environments.

The AP7343D-23FS4-7B\'s working principle involves regulating the output voltage by switching the current on and off with a control signal, modulating the switch state as needed to maintain the desired voltage. The regulated voltage is determined by the internal comparator, which compares the voltage at the output to a reference voltage. In temperature and noise resistant cases, the AP7343D-23FS4-7B is capable of keeping the output voltage very close to the reference voltage and has very low ripple and fast response times.

In addition to regulating the output voltage, the AP7343D-23FS4-7B provides an adjustable current limit feature to reduce and limit the amount of current being consumed. This feature is used to protect the device from damage due to excessive current consumption, improving system efficiency and stability. The AP7343D-23FS4-7B also has a very low quiescent current of only 0.75 mA, allowing it to use less power when operating in standby mode.

The AP7343D-23FS4-7B is designed to operate over a wide input voltage range of 4.5 V to 30 V and an output voltage ranging from 0.7V to 24 V. It has a maximum current rating of 5.0 A of continuous output current, 10.0 A of peak output current and can provide efficiencies up to 98%.

To ensure safety, the AP7343D-23FS4-7B is certified to meet IEC-61000-4-2 ESD, IEC-61000-4-4 surge, and IEC-60529 IP65 rated protection, making it suitable for industrial applications. In addition, it has a built-in over temperature protection (OTP) circuit and a thermal shutoff circuit to provide extra protection against overheating.

Overall, the AP7343D-23FS4-7B combines the best features of both linear and switching regulators, making it suitable for heavy-duty industrial applications. With its high efficiency, noise immunity and temperature rating, it\'s the ideal choice for any system looking for improved voltage regulation.
