S-8357F36MC-MGVT2G

Overview

The S-8357F36MC-MGVT2G is a non-isolated boost switching regulator controller manufactured by ABLIC Inc. It operates within a supply voltage range of 0.9V to 10V and delivers a fixed output voltage of 3.6V with a maximum output current capability of 1A. The device utilizes a PWM control scheme with a fixed switching frequency of 300kHz and supports a maximum duty cycle of 85%. Designed for surface-mount installation in an SOT-23-5 package, it functions reliably across an ambient temperature range of -40°C to +85°C.

Feature Summary

• Implements PWM control topology for efficient step-up voltage conversion
• Features CMOS output stage for driving external power switches
• Supports operation from low input voltages down to 0.9V

Applications

• Battery-powered portable electronic devices requiring voltage boosting
• General-purpose DC-DC power management circuits
• Embedded systems utilizing single-cell lithium-ion or alkaline batteries

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct output voltage and package configuration. Confirm RoHS compliance status and specific marking codes prior to integration. Cross-reference datasheet revisions to validate electrical characteristics and pinout assignments for the specific manufacturing batch.

Selection Notes

Select this component when a fixed 3.6V output is required from a variable input source between 0.9V and 10V. The 300kHz switching frequency allows for compact passive component selection compared to lower-frequency alternatives. Ensure the application demands a non-shutdown capable controller, as this specific variant lacks an enable pin interface.

Part Context

This unit belongs to the S-8357 series of switching controllers from ABLIC Inc., designed for cost-effective power management solutions. The series offers various fixed output voltage options within the same SOT-23-5 footprint, facilitating design flexibility. It serves as a core component in PMIC architectures for consumer electronics and industrial applications requiring reliable step-up regulation.

Replacement Considerations

Direct substitutes include other S-8357 series variants with different fixed output voltages, such as S-8357F33MC or S-8357F50MC, provided the system voltage requirements align. Verify that alternative parts maintain the same 300kHz frequency and SOT-23-5 package compatibility.
