S-8357F65MC-MHYT2U

Overview

The S-8357F65MC-MHYT2U is a step-up DC-DC switching controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 5.5V and provides a fixed output voltage of 6.5V. The device features a low quiescent current of 25.9µA and supports a switching frequency of 1MHz. It is housed in a compact SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency power MOSFET for compact design
• Supports both PWM and PFM modes for optimized efficiency
• Includes built-in protection against overcurrent and thermal overload

Applications

• Portable battery-powered electronic devices
• Low-voltage sensor power supplies
• Wearable technology circuits

Procurement Notes

Verify the specific suffix MHYT2U to confirm the fixed 6.5V output voltage and SOT-23-5 packaging configuration. Ensure compatibility with the required input voltage range of 0.9V to 5.5V for your target application before finalizing procurement.

Selection Notes

Select this component when a fixed 6.5V output is required from a single-cell lithium-ion or alkaline battery source. The 1MHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives, saving board space.

Part Context

This part belongs to the S-8357 series of step-up DC-DC controllers designed for ultra-low power consumption. It is engineered for applications requiring efficient power management from low-voltage sources while maintaining a small footprint through integrated components.

Replacement Considerations

Direct substitutes include other S-8357 variants with different fixed output voltages, such as S-8357F50MC-MHYT2U for 5.0V output, provided the system voltage requirements are adjusted accordingly.
