The S-8520B35MC-ARUT2G is a highly efficient DC-DC Buck Controller developed by Seiko. It is designed to be used in power supply applications such as electric vehicles, photovoltaic inverters, server and data centers, electric appliances and industrial control. This device is categorized into PMIC (Power Management IC) – Voltage Regulators - DC-DC Switching Controllers.

The S-8520B35MC-ARUT2G is an advanced single-channel buck controller that operates open-loop with a wide output voltage setting range from 0.6 V to 5.5 V. It allows for a high level of manipulation to boost the efficiency of a power supply system by operating in either a pulse-width modulation (PWM) or a pulse frequency modulation (PFM) mode. This device also integrates several safety features such as voltage and current monitoring, die temperature monitoring, an enable input, and thermal shutdown.

The device incorporates an on-board PMOS output switch to deliver high efficiency levels where the output voltage can be easily adjusted by external voltages or resistors. The S-8520B35MC-ARUT2G provides very fast load transient response and supports several operating ranges in order to meet various application requirements. This device also features a low standby current consumption, allowing for reduced power consumption when idle. As a result, the S-8520B35MC-ARUT2G is an ideal choice for power supply designs that require high efficiency, simple control, and low power consumption.

The S-8520B35MC-ARUT2G works on the principle of synchronous rectification to achieve high efficiency and power density. This device works by regulating the buck switch on and off times at a programmed frequency to create a buck voltage waveform. The feedback circuit then measures the output voltage, and the control loop adjusts the duty cycle to regulate the output voltage. The main feature of the synchronous rectification process is that the buck switch is always activated, regardless of the output voltage. This reduces power loss and increases efficiency.

The S-8520B35MC-ARUT2G is a high-efficiency DC-DC buck controller. It provides multiple protection, efficient power conversion and fast response, making it a perfect solution for power supply applications such as electric vehicles, photovoltaic inverters, server and data centers, electric appliances and industrial control. The device operates in either PWM or PFM modes to achieve high efficiency, and it features low power consumption in standby. As a result, it is a great choice for designs that require high efficiency, simple control and low-power consumption.
