S-8340A60AFT-T2-U

Overview

The S-8340A60AFT-T2-U is a synchronous step-down switching regulator manufactured by ABLIC Inc. It operates within an input voltage range of 2.7 V to 16 V and delivers a fixed output voltage of 6.0 V. The device integrates a high-efficiency power MOSFET and supports continuous output currents up to 1.5 A. Key electrical parameters include a typical quiescent current of 120 µA in operation and 1.5 µA in standby mode. It features a switching frequency of 1 MHz, selectable via an external resistor or internal setting. The IC provides comprehensive protection mechanisms including overcurrent protection (OCP), thermal shutdown (TSD), and undervoltage lockout (UVLO). It is housed in a compact HTSOP-II-8 package suitable for space-constrained applications.

Feature Summary

• Integrated synchronous rectification with built-in N-channel and P-channel power MOSFETs for high efficiency.
• Fixed 6.0 V output voltage option eliminates the need for external feedback resistors.
• Built-in protection functions including overcurrent protection, thermal shutdown, and undervoltage lockout.
• Low standby current consumption enables extended battery life in portable devices.

Applications

• Portable electronic devices such as smartphones and tablets requiring stable 6V rails.
• Industrial control systems and instrumentation powered by 12V or 24V buses.
• Automotive infotainment and telematics units operating from vehicle battery systems.
• Consumer electronics and IoT modules needing efficient step-down regulation.

Procurement Notes

Verify the specific suffix 'T2-U' corresponds to the correct tape-and-reel packaging quantity and lead-free status as defined in the official ABLIC datasheet. Confirm that the fixed 6.0 V output variant matches the system requirement, as other output voltages are available in the S-8340 series. Ensure compatibility with the required input voltage range and load current before finalizing procurement orders.

Selection Notes

Select this component when a fixed 6.0 V output is required from an input source between 2.7 V and 16 V. Consider the 1 MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Evaluate the 1.5 A current capability against peak load demands. The HTSOP-II-8 package is suitable for applications with limited PCB area. Verify thermal performance under maximum load conditions due to the integrated power stage.

Part Context

The S-8340A60AFT-T2-U belongs to the S-8340 series of synchronous buck converters from ABLIC Inc. This series is designed for general-purpose power management in portable and industrial applications. It complements other ABLIC PMIC offerings like linear regulators and boost converters, providing a complete solution for multi-rail power systems. The series emphasizes high efficiency and compact footprint.

Replacement Considerations

Direct pin-to-pin replacements may include other ABLIC models within the S-8340 series with different output voltages if adjustable, or comparable synchronous buck converters from manufacturers like Texas Instruments (e.g., TPS54xx series) or Analog Devices (e.g., LTC3xxx series). Verify electrical specifications, pinout compatibility, and thermal characteristics before substitution.
