S-8357F52MC-MHLT2G

Overview

The S-8357F52MC-MHLT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates with a fixed switching frequency of 300 kHz and delivers a regulated output voltage of 5.2 V. The device supports a maximum output current of 1 A and features a maximum duty cycle of 85%. It functions within an operating temperature range from -40°C to +85°C and utilizes a compact SOT-23-5 surface-mount package.

Feature Summary

• Integrates a PWM control mechanism for efficient voltage boosting
• Designed for non-isolated boost converter topologies
• Utilizes CMOS technology for low quiescent current operation

Applications

• Battery-powered portable electronic devices
• General-purpose power management in consumer electronics
• Systems requiring stable voltage from single-cell lithium batteries

Procurement Notes

Verify the specific suffix MHLT2G against official ABLIC documentation to confirm tape-and-reel packaging details and exact marking codes. Ensure compatibility with standard SOT-23-5 footprint designs. Cross-reference the datasheet revision date to validate thermal and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5.2 V output is required from a lower input voltage source. The 300 kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the 1 A limit under all operating conditions.

Part Context

This part belongs to the S-8357 series of switching regulators, which are designed for high-efficiency step-up applications. The series typically offers low standby current and compact packaging options suitable for space-constrained mobile and wearable devices.

Replacement Considerations

Direct substitutes include other S-8357 variants with different fixed output voltages, such as the S-8357F50MC or S-8357F36MC, provided the system design accommodates the voltage difference. Check pinout compatibility.
