What is the AP7343D-17W5-7?

The AP7343D-17W5-7 is a Linear Voltage Regulator from the PMIC (Power Management IC) family. It is a high current, low dropout (LDO) regulator with a maximum output current of 17A. The AP7343D-17W5-7 is ideal for applications such as DC-DC converters, GPUs, chipsets and ASICs.

Application Field

The AP7343D-17W5-7 is designed for GPU (Graphics Processing Unit), Chipset, ASIC, and DC-DC Converters applications. Its 17A maximum output current is suitable for any high-current and low voltage power supply requirements.

The AP7343D-17W5-7 offers provided a wide range of output voltages and it can operate up to +150°C junction temperature. This makes it suitable for automotive, industry, and industrial settings.

AP7343D-17W5-7\'s combination of low noise, low dropout voltage, and high efficiency makes it an ideal choice for applications with very tight space constraints. With a typical dropout voltage of only 0.4V, it can provide better electrical performance than many other linear voltage regulators on the market.

Working Principle

The AP7343D-17W5-7 is a low dropout (LDO) linear voltage regulator. It works by dropping the input voltage to the desired output voltage. This is done by dissipating the excess energy in the form of heat. The amount of energy dissipated depends on the difference between the input voltage and the output voltage. The higher the difference, the more energy is dissipated.

The AP7343D-17W5-7 has an integrated Thermal Shut Down (TSD) feature that limits the power dissipated in the device, thus preventing it from overheating. In case of prolonged high temperature operation, it will decrease the output current and enter the thermal shutdown mode.

The device also has built-in current limiting circuit that limits the output current to a safe level if the output current is reached beyond its rated current. The current limiting feature allows for safe operation and can prevent damage to the device and other components in the system.

Conclusion

The AP7343D-17W5-7 is a high current, low dropout linear voltage regulator from the PMIC (Power Management IC) family. It is ideal for applications such as DC-DC converters, GPUs, chipsets and ASICs, and has a maximum output current of 17A. The device offers high efficiency and low noise performance, and integrated Thermal Shut Down (TSD) to prevent the device from overheating. The current limiting circuit ensures safe operation, protecting both the device itself and other components in the system.
