Overview
The S-8340D00AFT-T2-U is a synchronous step-down switching regulator manufactured by ABLIC Inc. It operates within an input voltage range of 2.5 V to 6 V and provides a fixed output voltage of 1.2 V. The device integrates high-side and low-side N-channel MOSFETs, achieving a typical efficiency of 95% at 1 A load current. It features a wide switching frequency range from 200 kHz to 2.2 MHz, selectable via an external resistor. The IC includes comprehensive protection mechanisms such as overcurrent protection, thermal shutdown, and undervoltage lockout. It is housed in a compact HTSOP-J8 package.
Feature Summary
- Integrates high-side and low-side N-channel MOSFETs for high-efficiency power conversion
- Features adjustable switching frequency ranging from 200 kHz to 2.2 MHz
- Includes built-in protection functions against overcurrent, overheating, and undervoltage
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered equipment with single-cell lithium-ion power sources
- Embedded systems utilizing 3.3 V or 5 V input rails
Procurement Notes
Verify the specific suffix codes against official ABLIC documentation to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status and environmental certifications prior to integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and supply chain integrity.
Selection Notes
Select this component when a compact solution with integrated power switches is required for low-voltage applications. Consider the fixed 1.2 V output constraint and the need for external frequency-setting resistors. Evaluate the thermal performance requirements based on the expected load current and ambient operating conditions.
Part Context
This component belongs to the S-8340 series of synchronous buck converters designed by ABLIC. The series focuses on providing high efficiency and small footprint solutions for portable electronics. The S-8340D00AFT variant specifically offers a fixed 1.2 V output, distinguishing it from adjustable output models within the same family.
Replacement Considerations
Consult official ABLIC substitution guides for compatible alternatives. Verify pin compatibility and electrical specifications before replacing with other manufacturers' parts.
