S-8357F65MC-MHYT2G

Overview

The S-8357F65MC-MHYT2G is a step-up switching controller manufactured by 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 6.5V. The device features a switching frequency of 300kHz with a maximum duty cycle of 78%. It supports an output current of up to 54.8mA while maintaining a low quiescent current of 25.9uA. The component functions reliably across an operating temperature range from -40°C to +85°C and is housed in a surface-mount SOT-23-5 package.

Feature Summary

• Integrates a high-efficiency step-up topology optimized for battery-powered applications requiring stable voltage regulation.
• Incorporates ultra-low standby current consumption to maximize operational longevity in portable devices.
• Features built-in protection mechanisms including over-current limiting and thermal shutdown for enhanced system safety.

Applications

• Portable consumer electronics such as mobile phones and digital cameras
• Battery-operated handheld instruments and medical devices
• Wearable technology and smart home accessories

Procurement Notes

Verify the specific suffix MHYT2G against official ABLIC documentation to confirm tape-and-reel packaging specifications and marking codes. Ensure compatibility with standard SOT-23-5 footprint layouts during PCB design. Cross-reference RoHS compliance status directly with the manufacturer's latest environmental declarations prior to final procurement approval.

Selection Notes

Select this controller when a fixed 6.5V output is required from single-cell lithium-ion or alkaline batteries. Consider the 300kHz switching frequency for balancing component size and efficiency. Evaluate the 25.9uA quiescent current against strict power budget constraints typical in always-on portable applications.

Part Context

This component belongs to the S-8357 series of switching controllers, which are engineered for low-power DC-DC conversion. The series provides various fixed output voltages to suit different application needs while maintaining a consistent small-footprint package design suitable for space-constrained modern electronics.

Replacement Considerations

Direct substitutes within the same series include S-8357F50MC-MHJT2U for 5.0V output and S-8357G32MC-MIRT2U for 3.2V output. Verify pinout compatibility and thermal characteristics before substituting with other manufacturers' boost controllers.
