The S-8352D30MC-K8PT2U is a DC DC switching controller developed by Seiko Instruments Inc. This device is designed to provide efficient power converters up to 30V, with a maximum output current of 8A. It is a member of the PMIC - Voltage Regulators - DC DC Switching Controllers device family and it is suitable for applications such as industry automation, communications, consumer electronics, medical, and automotive.

The S-8352D30MC-K8PT2U has an input voltage range of 4.5V to 30V, with a 0.8V voltage drop across it. Its Quasi-resonant (QR) operating mode allows for high efficiency and low EMI, while its high-speed operation allows for a fast response time and stable operation. It also has a high-speed frequency jittering functions to reduce EMI. The device also features under-voltage lockout (UVLO), over-current protection (OCP) and over-temperature protection (OTP).

The S-8352D30MC-K8PT2U is also equipped with a low power consumption mode for power saving applications. This mode allows for a quiescent current of as low as 20uA, reducing the losses from the system. It also supports remote sense output voltage adjustment and current control functions. It has an on-chip clock frequency modulation circuitry, enabling adjustable switching frequency. This means that different frequency settings can be applied to different applications, allowing flexibility to meet system requirements.

The S-8352D30MC-K8PT2U works in two stages. First, an internal voltage comparator monitors the input voltage and triggers an appropriate response if any voltage anomalies are detected. Second, an on-chip power switch is activated to maintain an output voltage in accordance with the input voltage. The device can also adjust the output current by setting different duty cycles. The power switch is enabled by a pulse-width modulation (PWM) logic, and the duty cycle can be adjusted by changing the period of the PWM signal.

In summary, the S-8352D30MC-K8PT2U is a reliable device for diode-rectifier and switching DC DC converters. It provides efficient power within a wide input voltage range. It is suitable for many applications, from industry automation, communications, med-tech, and automotive. It also has great features such as low power consumption mode and adjustable switching frequency.
