S-8357B25MC-NIKT2G

Overview

The S-8357B25MC-NIKT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9 V to 10 V and provides a fixed output voltage of 2.5 V. The device supports a maximum output current of 100 mA with a switching frequency of 300 kHz. It features a maximum duty cycle of 85% and maintains a low operating supply current of 68.6 uA. The component is 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 a high-efficiency boost converter topology for non-isolated DC-DC conversion
• Features a CMOS output stage designed for driving external power switches
• Operates with a wide input voltage range compatible with single-cell lithium-ion batteries

Applications

• Portable electronic devices requiring stable voltage from single-cell sources
• Battery-powered sensor modules needing regulated power supplies
• Industrial control systems utilizing low-voltage input sources

Procurement Notes

Verify the specific suffix NIKT2G against official ABLIC documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure the ordering quantity aligns with manufacturer minimums. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V output is required from inputs as low as 0.9 V. The 300 kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the external switch can handle the 100 mA output current requirement and that the PCB layout supports the SOT-23-5 thermal characteristics.

Part Context

This part belongs to the S-8357 series of switching regulators from ABLIC. The series is characterized by high efficiency and low standby current, targeting battery-operated applications. The S-8357 family utilizes a PWM control method to maintain regulation under varying load conditions while minimizing power consumption during operation.

Replacement Considerations

Direct replacements include other S-8357 variants with different output voltages or current ratings, such as the S-8357F36MC-MGVT2G. Ensure the substitute maintains the same SOT-23-5 footprint and compatible input voltage range.
