PMIC - RMS to DC Converters, such as the AD536ASE/883B, are integrated circuits that range from amplifiers to filters, clocks, regulators and switching circuits. They are used to convert the Root Mean Square (RMS) of an alternating current (AC) signal into the corresponding Direct Current (DC) signal. The main application for this type of converter is for controlling and converting power in systems with multiple voltages, such as in multiple-voltage DC-DC power supplies.

The AD536ASE/883B RMS-to-DC converter operates by first truncating the AC signal to a manageable level with a high pass filter. The signal is then amplified and rectified before passing to a rectifying element. The rectifying element takes both the amplitude, or peak-to-peak value, and the frequency of the incoming AC signal and converts it into a DC output. The output is then passed through an adjustable voltage-proportioning element, which sets the DC voltage level that is desired.

The AD536ASE/883B converter is designed to provide maximum efficiency and output accuracy over the designated frequency range, while also providing robust protection against surges and transients. Its noise immunity and accuracy make it suitable for use in many types of applications, including single-to-three-phase and three-to-nine-phase convertors, power supply output voltage regulation, motor speed and current control, and refrigeration and air conditioning temperature and speed control.

In terms of performance, the AD536ASE/883B converter can handle up to 40-kiloohm load levels and has an output accuracy of within 1 percent. It also features a high input impedance, allowing it to efficiently process AC signals with small-amplitude levels without the need for additional amplifying circuits. It is also suitable for use in low-frequency small-signal and high-frequency large-signal applications, as well as for power-supply stabilization and for controlling overvoltage or undervoltage conditions including lightning protection.

In conclusion, the AD536ASE/883B RMS-to-DC converter is a highly efficient and useful integrated circuit that can convert AC signals into DC signals efficiently and with a high degree of accuracy. It is suitable for use in a variety of applications including frequency control, motor speed and current control, refrigeration and air conditioning temperature control, and power-supply output voltage regulation. Its integrated protection features make it an ideal choice for use in applications where noise immunity and accuracy are paramount.
