S-8520C50MC-BSJT2G

Overview

The S-8520C50MC-BSJT2G is a step-down DC-DC switching controller manufactured by ABLIC Inc. It operates within an input voltage range of 2.5V to 16V and provides a fixed output voltage of 5V. The device utilizes a buck topology with a maximum duty cycle of 100% and supports a switching frequency of 180kHz. It is housed in a compact SOT-23-5 package, suitable for surface mount installation. The component functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Supports 100% duty cycle operation for efficient low-dropout performance
• Integrates enable control functionality for power management
• Designed for single-output positive voltage regulation

Applications

• Battery-powered portable electronic devices
• Embedded systems requiring stable 5V logic supply
• Industrial equipment with 2.5V to 16V input rails

Procurement Notes

Verify the specific suffix 'BSJT2G' against official ABLIC documentation to confirm exact marking codes and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required from inputs up to 16V. The 180kHz switching frequency balances component size and efficiency. Verify that the load current requirements do not exceed the external switch capabilities, as this is a controller IC rather than a complete regulator module.

Part Context

This part belongs to the S-8520 series of buck switching controllers from ABLIC. The series is characterized by its ability to operate at high duty cycles and its compact SOT-23-5 packaging. It serves as a core control element in power management designs where space constraints and input voltage flexibility are critical design parameters.

Replacement Considerations

Check for direct pin-compatible alternatives within the S-8520 family or the S-8521 series if different output voltages or switching frequencies are needed. Ensure any substitute maintains the 2.5V to 16V input range and SOT-23-5 footprint.
