S-8357B60MC-NJTT2G

Overview

The S-8357B60MC-NJTT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 10V and provides a fixed output voltage of 6.0V. The device features a switching frequency of 300kHz and supports a maximum duty cycle of 78%. It delivers an output current capability of 54.8mA with a typical quiescent current of 25.9uA. The component functions in a non-isolated topology and is housed in a compact SOT-23-5 package, suitable for surface mount installation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency boost converter topology for efficient voltage stepping.
• Features low quiescent current consumption to extend battery life in portable applications.
• Utilizes a compact SOT-23-5 package for space-constrained designs.

Applications

• Battery-powered portable electronic devices
• Consumer electronics requiring voltage boosting
• Industrial control systems

Procurement Notes

Verify the specific suffix NJTT2G against official ABLIC documentation to confirm tape and reel packaging specifications. Ensure compatibility with standard SMD/SMT assembly processes for the SOT-23-5 footprint. Cross-reference the part number with authorized distributors to confirm RoHS compliance status and availability of the latest datasheet revisions prior to final procurement.

Selection Notes

Select this component when a fixed 6.0V output is required from a single-cell lithium-ion or similar battery source. The 300kHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the load current does not exceed the 54.8mA limit and that the input voltage remains within the 0.9V to 10V operational window for stable regulation.

Part Context

This part belongs to the S-8357 series of switching regulators from ABLIC. The series offers various fixed output voltages and packages. The S-8357B60 variant specifically targets applications needing a 6.0V output. It shares common family characteristics such as the SOT-23-5 package option and PWM control mechanism found across the broader S-8357 lineup.

Replacement Considerations

Direct substitutes include other S-8357 series variants with different output voltages if system requirements change, such as S-8357F50MC-MHJT2U for 5.0V output. Ensure pinout compatibility and thermal performance match when considering cross-series replacements from ABLIC or competitors.
