S-8366AABBA-I6T1U2

Overview

The S-8366AABBA-I6T1U2 is a non-isolated step-up switching controller manufactured by ABLIC. It operates with a fixed switching frequency of 1.2 MHz and supports PWM/PFM modes. The device accepts an input voltage range of 0.9 V to 5.5 V and provides a regulated output voltage of 6.0 V. It features a shutdown function for power management and operates within a temperature range of -40°C to +85°C. The component is housed in an SNT-6A package.

Feature Summary

• Integrated step-up topology for efficient voltage boosting
• Supports both PWM and PFM control modes for optimized efficiency
• Includes a dedicated shutdown pin for low-power standby operation

Applications

• Portable electronic devices requiring voltage boosting
• Battery-powered systems needing stable higher voltage rails
• General-purpose DC-DC conversion in compact form factors

Procurement Notes

Verify the specific suffix I6T1U2 against the manufacturer's latest datasheet to confirm pinout and electrical characteristics. Confirm availability status as components may be subject to discontinuation or supply constraints. Ensure compatibility with your PCB footprint, specifically the SNT-6A package dimensions. Cross-reference RoHS compliance requirements with your assembly standards before finalizing procurement orders.

Selection Notes

Select this controller when a fixed 6.0 V output is required from a variable input source between 0.9 V and 5.5 V. The 1.2 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the shutdown feature if system power management requires active sleep states. Verify that the load current requirements fall within the controller's operational limits defined in the official specifications.

Part Context

This part belongs to the S-8366 series of step-up switching controllers from ABLIC. The series is designed for applications requiring efficient voltage regulation in space-constrained environments. The SNT-6A package offers a compact solution suitable for modern surface-mount assembly processes. This specific variant integrates fixed output voltage settings to simplify circuit design.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult ABLIC directly for qualified replacements or verify compatibility with alternative boost controllers offering similar 1.2 MHz frequencies and SNT-6A packaging.
