Overview
The S-8340A50AFT-T2-U is a CMOS step-up switching regulator controller manufactured by ABLIC Inc. It belongs to the S-8340/8341 series and is housed in an 8-TSSOP package. The device functions as a voltage regulator controller for boost applications, utilizing an internal reference voltage to manage external power switches. It is designed for DC-DC conversion tasks requiring precise control of step-up topology.
Feature Summary
- Functions as a dedicated controller for step-up (boost) switching regulators
- Integrates a precision internal reference voltage source
- Designed for driving external power transistors in DC-DC converter circuits
Applications
- Battery-powered portable devices requiring voltage boosting
- Industrial equipment power management systems
- General-purpose DC-DC step-up converter designs
Procurement Notes
Verify the specific output configuration and driver requirements against the official S-8340 datasheet before integration. Confirm that the 8-TSSOP package dimensions match the target PCB footprint. Ensure compatibility with external components selected for the boost topology.
Selection Notes
Select this component when a discrete controller solution is preferred over integrated switching regulators. It allows flexibility in choosing external MOSFETs and inductors to meet specific current and efficiency targets. Suitable for designs where standard fixed-frequency controllers do not provide sufficient customization.
Part Context
This part is part of the S-8340/8341 series from ABLIC, which focuses on CMOS step-up switching regulator controllers. These ICs are distinct from complete switching regulators as they require external power switches. The series supports various input and output voltage configurations depending on external component selection.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other boost controllers if direct substitution is required.
