The LM3622AMX-8.4 is a configurable, single-output, switch-mode power supply for applications that require multiple power rails. It features high efficiency and precision control over the voltage and current output. The LM3622AMX-8.4 is designed to replace multiple complex power supply solutions with just one simple solution.

The LM3622AMX-8.4 belongs to the field of PMIC (Power Management Integrated Circuits) and is part of the Battery Chargers range. It is a low-cost and low-power solution for many types of applications.

The device includes an integrated switching regulator, one or two low-dropout (LDO) linear regulators, and five configurable bias circuits. The wide input voltage range makes it suitable for applications where multiple power supply solutions are needed. Furthermore, the voltage and current control is improved with the on-chip temperature compensator and current share function.

The power supply switching converter regulates the output voltage using a combination of Pulse Frequency Modulation (PFM) and Pulse Width Modulation (PWM) control. This converter combines high efficiency and low output noise to ensure precise control over the voltage and current output.

The two independent LDOs regulate the multiple output voltages. The linear regulators are configured with a low-dropout voltage, allowing for operation in a wide range of input voltages. The on-chip temperature compensator provides precise control over the regulated voltages over temperature, making the LM3622AMX-8.4 suitable for use in industrial and consumer applications.

The five configurable bias circuits provide a low-power, low-frequency reference voltage for many power supply solutions. The bias circuits are designed to work in tandem with the mainline regulator to provide a low-power and precise reference voltage.

The LM3622AMX-8.4 is available in a compact 8-pin thermally enhanced MLPQ package. It is compatible with most of the popular controllers, as well as with several discrete control options. The device is certified for automotive operation and complies with the highest industry requirements for quality and reliability.

The LM3622AMX-8.4 can operate from an input voltage of 4.5V up to 28V. Its peak efficiency is over 85%, with load regulation of less than 0.5%. The device can be used in multiple applications including power supplies, industrial AC/DC converters and chargers.

The LM3622AMX-8.4 is highly configurable and versatile, making it the ideal choice for a wide range of applications requiring accurate power supply solutions. Its small size, high efficiency, and precise control make it an excellent choice for applications ranging from consumer electronics to industrial applications.
