S-8355K20MC-NAFT2G

Overview

The S-8355K20MC-NAFT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates at a fixed switching frequency of 600 kHz and utilizes PWM control. The device supports an input voltage range from 0.9 V to 10 V and delivers a regulated output voltage of 2.0 V. It is housed in a compact SOT-23-5 package, suitable for surface-mount applications.

Feature Summary

• Integrated step-up switching regulator controller with fixed 600 kHz operation
• Supports wide input voltage range up to 10 V
• Compact SOT-23-5 package design

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing voltage boosting
• General-purpose DC-DC conversion circuits

Procurement Notes

Verify the specific suffix NAFT2G against official ABLIC documentation to confirm tape-and-reel packaging and marking codes. Ensure compatibility with standard SOT-23-5 footprint designs. Cross-reference RoHS compliance status directly with the manufacturer's current datasheet revision.

Selection Notes

Select this component when a fixed 600 kHz boost controller is required within a 10 V input limit. The 2.0 V output specification suits low-voltage load requirements. Evaluate thermal performance based on the SOT-23-5 package constraints for the intended application environment.

Part Context

This part belongs to the S-8355 series of super-small package step-up controllers. The series is characterized by high-frequency operation and compact form factors designed for space-constrained portable electronics. It complements other variants offering different output voltages or control modes within the same family.

Replacement Considerations

Direct substitutes include other S-8355 series variants with compatible pinouts and similar electrical characteristics. Verify that alternative parts match the 600 kHz frequency and 2.0 V output requirement without requiring circuit redesign.
