S-8356K50MC-NFJT2G

Overview

The S-8356K50MC-NFJT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 5V. The device features a low quiescent current of 25.9uA and supports a switching frequency of 600kHz with a maximum duty cycle of 85%. It utilizes a synchronous rectification architecture without clock synchronization, housed in a compact SOT-23-5 package suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates synchronous rectification control for efficient power conversion
• Maintains ultra-low standby current consumption during operation
• Supports wide input voltage ranges for flexible system integration

Applications

• Battery-powered portable electronic devices
• Low-power sensor node power management
• IoT module supply regulation

Procurement Notes

Verify the specific suffix NFJT2G against official ABLIC documentation to confirm tape-and-reel packaging specifications and marking codes. Ensure compatibility with standard SMD reflow profiles for the SOT-23-5 package. Cross-reference the part number with authorized distributors to validate current availability status and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when a fixed 5V output is required from variable or low-voltage sources. The 600kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the load current requirements remain within the controller's capability when paired with appropriate external switches.

Part Context

This part belongs to the S-8356 series of switching regulators designed for high efficiency and low power consumption. It complements other variants in the lineup offering different fixed output voltages, such as 3V or 3.3V, allowing designers to maintain consistent design methodologies across various power rail requirements within a single product family.

Replacement Considerations

Direct substitutes include S-8356M30MC-MEPT2U for 3V output and S-8356Q50MC-OVJT2G for identical 5V output functionality. Ensure pinout compatibility and thermal performance match the original design constraints before swapping.
