The S-8357B50UA-NJJT2U is an integrated circuit (IC) switch-mode DC-DC controller. It is designed to enable the power-supply designer to achieve a low cost, high performance and fast-response point-of-load (POL) power solution that operates over a full input range of 3.5V-17V. The IC also offers exceptionally high accuracy, with a tight voltage regulation of ±10.0 mV (typical) for most of the output voltage range.
The S-8357B50UA-NJJT2U is a highly integrated, high-efficiency DC-DC controller that can operate from either an input voltage of 3.5V or an output voltage of up to 17V. It provides dual control loops and advanced protections, including overcurrent protection, short-circuit protection, and over-temperature protection. The controller features an advanced LOAD-DIS array of current sensing, which allows for fast and accurate current monitoring. Additionally, it offers a sleep mode, which enables the controller to store and retrieve its settings for low power consumption.
The S-8357B50UA-NJJT2U works by using a P-channel, N-channel topology MOSFET power switch, which allows it to minimize power losses by switching rapidly between two different voltage and current states. During pulse width modulation (PWM), the IC monitors the output voltage and sends a signal to adjust the duty cycle of the MOSFET switch accordingly. This helps to maintain a stable, regulated DC voltage output.
The IC is suitable for a range of different applications. It can be used in Li-Ion battery-powered systems, such as mobile phones, to help save power while preserving a constant, regulated voltage. It is also suitable for wireless charging systems and battery powered medical equipment. Additionally, it can be employed in the point-of-load regulation of distributed systems, providing high performance, fast transient response and a small size.
In summary, the S-8357B50UA-NJJT2U is a versatile, low-cost and high-efficiency IC that can power both linear and switch-mode DC-DC applications. Its high accuracy and fast response provide added benefits for demanding power-supply systems. And its sleep mode allows for low power consumption, making it suitable for battery-powered systems.
