The S-8354A30MA-JQPT1U is a DC-DC switching regulator integrated circuit from Renesas Corporation. It is part of the DC-DC switch regulator family, which includes a wide selection of high-performance devices for generating power management solutions. The S-8354A30MA-JQPT1U has a maximum output current of 3 A and an input voltage range from 7.5 V to 30 V, making it an ideal choice for applications requiring a wide input voltage range. In addition to providing an adjustable output voltage, the S-8354A30MA-JQPT1U is equipped with over-temperature protection, over-current protection, and short-circuit protection.

The S-8354A30MA-JQPT1U is widely used in various applications, such as automotive and industrial electronics, consumer electronics, home security systems, medical equipment, and wearable devices. It is also suitable for powering LED lighting, motor control, and portable battery-operated applications due to its high-efficiency and low power consumption. The device has integrated circuit protection features and adjustable output voltage enabling efficient power supply designs with tight load and line regulation.

The S-8354A30MA-JQPT1U features a step-down switching regulator that can be used to provide a regulated voltage from an input supply voltage at a lower level than the input voltage. This is accomplished by using an internal Pulse Width Modulated (PWM) controller and an external MOSFET, inductor, and output capacitor. The PWM controller turns the MOSFET on and off in order to generate an output voltage line that is maintained at a desired level.

The switching frequency of the S-8354A30MA-JQPT1U is adjustable and it can range from 50KHz to 1MHz depending on specific application requirements. The device also has an adjustable current limit which can limit the output current to up to 3A to protect itself in case of overload. The over-temperature protection can detect if the operating temperature of the device exceeds 150°C and will shut down the device when this occurs to prevent any damage from occurring. Finally, the S-8354A30MA-JQPT1U also features Under-Voltage Lockout (UVLO) which ensures that the device does not start working until the voltage level of the input lines is above the minimum level.

The S-8354A30MA-JQPT1U is a highly integrated, high-efficiency DC-DC switching regulator and one of the most popular power management integrated circuits in the market today due to its wide input voltage range, adjustable current limit, and comprehensive protection features. Its ability to produce a stable and accurate output voltage with a wide range of input voltage makes it suitable for a variety of automotive, industrial, consumer, and medical applications.
