S-8355K24MC-NAJT2G

Overview

The S-8355K24MC-NAJT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates at a fixed frequency of 600 kHz and supports PWM control or switchable PWM/PFM modes. The device features a wide input voltage range of 0.9 V to 10 V and delivers a fixed output voltage of 2.4 V. It is housed in a super-small SOT-23-5 package, suitable for surface mount applications with an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports switchable PWM or PWM/PFM control modes for optimized efficiency
• Integrates a built-in oscillator for stable 600 kHz operation
• Features a compact SOT-23-5 package design for space-constrained layouts

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems utilizing single-cell lithium-ion or lithium-polymer sources
• Embedded circuits needing regulated voltage from low input sources

Procurement Notes

Verify the complete part number including suffixes such as NAJT2G to ensure correct packaging and marking specifications. Confirm that the required output voltage matches the fixed internal setting of 2.4 V. Check compatibility with external components like inductors and capacitors against the official datasheet recommendations. Ensure supply chain channels provide genuine ABLIC products with valid traceability documentation.

Selection Notes

Select this component when a fixed 2.4 V output is required from a variable input source between 0.9 V and 10 V. Consider the switchable control mode if system efficiency varies significantly across load conditions. Evaluate the SOT-23-5 footprint against available board space. Verify thermal performance requirements within the -40°C to +85°C operational range for the specific application environment.

Part Context

This model belongs to the S-8355 series of step-up switching regulator controllers from ABLIC. The series is characterized by its small package size and flexible control options. Variants within the family differ primarily in fixed output voltage settings and specific ordering suffixes for packaging. This particular unit provides a 2.4 V output configuration.

Replacement Considerations

Direct replacements must match the S-8355 series architecture, 600 kHz frequency, and SOT-23-5 package. Verify that alternative parts support the same 2.4 V fixed output and 0.9 V to 10 V input range. Cross-reference pinouts and control logic compatibility before substitution.
