Overview
The S-8540A33FN-IAST2G is a synchronous rectification switching regulator (DC-DC converter) manufactured by ABLIC Inc. It provides a fixed output voltage of 3.3V with a maximum output current capability of 1A. The device accepts an input voltage range up to 36V, with an absolute maximum rating of 45V. It operates within an ambient temperature range of -40°C to +125°C and is housed in a compact HSNT-8(2030) package measuring 3.0 x 2.0 x 0.5mm.
Feature Summary
- Synchronous rectification architecture for high efficiency
- Compact footprint utilizing industry-standard small package
- Wide input voltage tolerance for robust operation
Applications
- Industrial equipment power management
- Automotive domain controllers
- Battery-powered portable devices
Procurement Notes
Verify the specific suffix 'IAST2G' against official datasheets to confirm tape-and-reel packaging quantities and marking codes. Ensure the ordering part number matches the exact pin configuration and thermal pad requirements specified in the manufacturer's documentation before finalizing procurement.
Selection Notes
Select this component when a 3.3V rail is required with up to 1A load current in space-constrained designs. The wide input range supports direct connection to higher voltage buses without pre-regulation. Verify that the thermal performance of the HSNT-8 package meets the system's dissipation requirements under maximum load conditions.
Part Context
This part belongs to the S-8540 series of DC-DC converters from ABLIC. The series is characterized by its integration of synchronous rectification to minimize power loss and its ultra-small package size, designed specifically for modern electronics requiring high power density and efficient voltage conversion.
Replacement Considerations
Check for compatible parts within the same S-8540 family or other ABLIC synchronous buck regulators offering identical 3.3V output and 1A current capacity. Ensure pin-to-pin compatibility and equivalent thermal characteristics if substituting.
