PMIC - Voltage Regulators - DC DC Switching Controllers: S-8365ABBAA-M6T1U2 Application Field and Working Principle

The S-8365ABBAA-M6T1U2 (S-8365) is an integrated circuit (IC) from the family of DC DC switching controllers from Rohm – a major manufacturer of integrated circuits, transistors, and diodes in the electronics industry.

The DC DC switching controller is a type of voltage regulator specifically intended to provide a stable output while converting a power supply between different input and output voltages. This is achieved by switching between different types of current in order to control the voltage. This type of voltage regulator is able to convert a constant input voltage – either AC or DC – into a constant, predetermined output voltage.

The S-8365 is specifically designed to control an isolated DCDC (double conversion) converter. This offers many advantages over linear regulators, such as providing higher efficient conversions with lower power losses. Its burning is also extended, due to its superior efficiency, allowing it to operate for lengthy periods of time.

The S-8365, in particular, contains a resonant control circuit and two output MOS transistor driver circuits. The resonant control circuit is essential for DCDC converter functions and switching, while the two drivers aim to achieve peak efficiency in the circuits, thanks to their fast switching speeds.

The S-8365 is also designed for a wide operating temperature range of -40°C to +125°C, making it ideal for harsh industrial applications. In addition, it has a low dropout voltage and supports a maximum duty cycle of 85%.

The S-8365 is a versatile voltage regulator and is commonly used in a variety of industrial and medical equipment. These include portable medical equipment, uninterruptible power supplies (UPS), and power supplies for telecommunications equipment. It is also great for large data centers and industrial automation systems, where power consumption is paramount.

This versatile voltage regulator also features a variety of features that make it well-suited for a number of applications. These features include: a sleep mode for low power consumption, a watchdog timer for system protection, an internal analog delay, and an internal PWM generator for controlling pulse widths.

The working principle of the S-8365 is based on the concept of self-oscillation, which helps the device to achieve pulse width modulation (PWM). When an input voltage is supplied to the regulator, the outer loop controls the current source, which regulates the converter. The inner loop then monitors the output voltage, and adjusts the current source as required until the desired voltage level is reached.

In summary, the S-8365 is a versatile DCDC switching controller suitable for a wide array of industrial and medical applications. It features a low dropout voltage, fast switching speeds, and a low power sleep mode. With its wide operating temperature range and advanced features, it is a great choice for those who need reliable voltage regulation and a low power solution.
