S-8358F33MC-MKST2G

Overview

The S-8358F33MC-MKST2G is a step-up switching controller from ABLIC Inc., designed for efficient power management in compact electronic systems. It operates within a supply voltage range of 0.9V to 10V and delivers a fixed output voltage of 3.3V. The device features an ultra-low standby current of 25.9uA, ensuring minimal power consumption during idle states. It supports both PWM and PFM modes for optimized efficiency across varying load conditions. The component is housed in a small SOT-23-5 package, suitable for surface-mount applications, and functions reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates ultra-low standby current capability to extend battery life in portable devices.
• Supports flexible switching operation with combined PWM and PFM control modes.
• Delivers stable regulated output voltage through integrated feedback loop mechanisms.

Applications

• Battery-powered portable electronics requiring low quiescent current
• Compact consumer devices with limited board space constraints
• IoT sensors and modules needing efficient step-up regulation

Procurement Notes

Verify the exact suffix MKST2G against official ABLIC documentation to confirm tape-and-reel packaging specifications and marking codes. Ensure compatibility with standard SMD reflow profiles for SOT-23-5 packages. Cross-reference RoHS compliance status using the manufacturer's latest environmental declaration. Confirm availability through authorized distributors only to avoid counterfeit components.

Selection Notes

Select this model when fixed 3.3V output is required alongside minimal standby current consumption. Consider the SOT-23-5 footprint for space-constrained designs. Evaluate input voltage ranges against system requirements to ensure operation within the 0.9V to 10V limit. Compare switching frequency characteristics if EMI sensitivity is a concern in the target application environment.

Part Context

Part of the S-8358 series, which includes various output voltage options and package variants. Shares common control architecture with other members like S-8358E15MC-NSAT2U and S-8358H23MC-NUIT2G. Designed as a cost-effective solution for basic step-up conversion tasks without requiring external compensation networks.

Replacement Considerations

S-8358J33MC-NWST2U offers identical electrical performance with different marking code suffixes. S-8358H23MC-NUIT2G provides similar functionality but with a different output voltage setting. Verify pinout compatibility before substitution to ensure direct replacement feasibility.
