S-8365AAABA-I6T1U2

Overview

The S-8365AAABA-I6T1U2 is a non-isolated boost switching controller manufactured by ABLIC Inc. It operates within an input voltage range of 1.8 V to 5.5 V and supports a switching frequency of 600 kHz. The device features a maximum duty cycle of 95% and includes a shutdown function for power management. It is housed in an SNT-6A-6 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM control modes for efficient step-up voltage conversion
• Includes built-in short-circuit protection mechanisms
• Features UVLO (Under-Voltage Lockout) functionality

Applications

• Battery-powered portable electronic devices
• Low-voltage DC-DC conversion systems
• Power management circuits requiring shutdown capabilities

Procurement Notes

Verify the specific suffix I6T1U2 against official ABLIC documentation to confirm pinout and electrical characteristics. Confirm current availability status as some sources indicate end-of-life or limited stock conditions. Ensure compatibility with required packaging formats such as cut tape or reel before ordering.

Selection Notes

Select this component when a compact boost controller is needed for low-power applications. The SNT-6A-6 package suits space-constrained designs. Verify that the 600 kHz frequency meets EMI requirements and that the 1.8 V minimum input aligns with the source voltage profile.

Part Context

This part belongs to the S-8365 series of DC-DC switching controllers designed for battery-operated equipment. It complements other ABLIC PMIC solutions by providing efficient step-up regulation in a small footprint, targeting consumer electronics and industrial sensors.

Replacement Considerations

Check for direct substitutes within the S-8365/8366 series. Verify pin compatibility and electrical parameters before replacing.
