PMIC (Power Management IC) or usually referred as voltage references are integrated circuits used to maintain upper and lower voltage limits in power systems. The voltage reference also contains a voltage regulator to keep the output voltage within a narrow range. The most popular form of this IC is the ADR5043AKSZ-REEL7. This versatile, economical and reliable PMIC is used in industrial, automotive and consumer applications.

Applications and Working Principle of ADR5043AKSZ-REEL7

ADR5043AKSZ-REEL7 is ideal for applications that require a stable and reliable voltage source, such as motor controllers, gaming systems and smart home applications. Thanks to its high accuracy of +/- 0.05%, it is also suitable for high precision systems such as testing and measuring equipment. The IC is also treated with an electrostatic discharge (ESD) protection system, with an ESD rating of 2kV.

The main purpose of the ADR5043AKSZ-REEL7 is to convert the input voltage (typically 5 - 45V) into a stable output voltage (2.5, 3, 3.3, 5 or 12V depending on the part) with a very low ripple. This is accomplished through a two-stage architecture. The first stage rectifies the input voltage, and the second stage filters the now DC signal and regulates it to the desired output voltage.

The ADR5043AKSZ-REEL7 also offers excellent thermal performance and is designed to safeguard itself against short-circuits, over-temperature, over-voltage and under-voltage situations. The IC is also protected against reverse voltage as long as the applied voltage does not exceed the absolute maximum voltage.

Output Voltage Range and Control Capabilities

ADR5043AKSZ-REEL7 can produce different output voltages with a very low ripple. The output voltage range can be adjusted from 2.5 V to 12V depending on the part, but the input voltage is adjustable from 5 - 45V depending on the part as well. The output power of the device is also limited to up to 5A, which can be suitable for most applications.

The IC also provides several control features such as power-down, shutdown, and wake-up functions in order to optimize the power management of the system. The ADR5043AKSZ-REEL7 also has a PWM control pin that can be used to adjust the output voltage for fine tuning

Package Options and Operating Temperature Range

ADR5043AKSZ-REEL7 is available in several packages depending on the manufacturer, such as 3-Pin (SOIC-3) or 5-Pin (TSOT-5) packages. The operating temperature range of the IC is between -40 and 105ºC, making it suitable for a broad range of applications.

In conclusion, the ADR5043AKSZ-REEL7 is a very versatile, effective and reliable PMIC designed to be used in numerous applications. Its low drift and ripple characteristics make it suitable for high precision systems. Additionally, its high switching frequency allows for fast and efficient power conversion. Finally, its ESD rating of 2000V makes it safe for use in a wide variety of industrial, automotive and consumer devices.
