S-8358F26MC-MKLT2G

Overview

The S-8358F26MC-MKLT2G is a step-up switching controller manufactured by ABLIC Inc., belonging to the S-8358 series. It operates with a fixed output voltage of 2.6 V and supports an input supply range of 0.9 V to 10 V. The device integrates PWM/PFM control modes to optimize efficiency across varying load conditions, achieving a typical quiescent current of 25.9 uA. It functions within a temperature range of -40°C to +85°C and utilizes a compact SOT-23-5 surface-mount package.

Feature Summary

• Integrates low-quiescent-current step-up DC-DC controller for battery-powered applications
• Supports automatic transition between PWM and PFM modes for high efficiency at light loads
• Includes built-in oscillator and error amplifier for stable voltage regulation

Applications

• Portable electronic devices requiring extended battery life
• Low-power sensor nodes in IoT networks
• Battery-operated medical monitoring equipment

Procurement Notes

Verify the specific suffix MKLT2G 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 latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.6 V output is required from a single-cell lithium-ion or alkaline battery source. The low standby current makes it suitable for systems with strict power budget constraints. Verify that the external inductor and capacitor values align with the internal switching frequency specifications provided in the datasheet.

Part Context

This part belongs to the S-8358 family of ultra-low power step-up controllers designed for portable electronics. The series offers various fixed output voltages to accommodate different system requirements while maintaining consistent performance characteristics and pinout configurations across the product line.

Replacement Considerations

Consult the official ABLIC replacement guide for direct equivalents. Verify pin compatibility and electrical parameters before substituting with other manufacturers' boost controllers.
