S-8356K33MC-NEST2G

Overview

The S-8356K33MC-NEST2G 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 delivers a fixed output voltage of 3.3 V. The device supports a maximum switch current of 1.4 A and functions at a switching frequency of 600 kHz. It features a low quiescent current of 25.9 uA and includes built-in soft-start, overcurrent protection, and thermal shutdown mechanisms. The component is housed in a compact SOT-23-5 package and is rated for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM control modes for optimized efficiency across varying load conditions
• Includes comprehensive protection features such as overcurrent limiting and thermal shutdown
• Supports external enable pin control for flexible power management sequencing

Applications

• Battery-powered portable electronic devices requiring efficient voltage boosting
• Industrial equipment with single-cell lithium-ion battery inputs
• Automotive infotainment systems operating under variable supply conditions

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to ensure correct output voltage and package configuration. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Cross-reference the part number with authorized distributors to validate authenticity and traceability. Ensure that the ordering quantity aligns with standard reel packaging requirements specified by the supplier.

Selection Notes

Select this component when a fixed 3.3 V output is required from a wide input voltage range up to 10 V. Consider its 600 kHz switching frequency for applications prioritizing smaller passive component sizes. Evaluate the 1.4 A switch current capability against peak load demands. Verify compatibility with external inductor selection based on the specified switching parameters.

Part Context

This part belongs to the S-8356 series of step-up switching regulators from ABLIC. The series is designed for high-efficiency power conversion in space-constrained applications. Similar models in the lineup offer different fixed output voltages or current ratings while maintaining the same core control architecture and protection features.

Replacement Considerations

Direct substitutes include S-8356Q50MC-OVJT2U and S-8356M30MC-MEPT2G. Verify output voltage compatibility before substitution. Check package pinout alignment to ensure mechanical interchangeability without PCB redesign.
