S-8521E30MC-BLPT2U

Overview

The S-8521E30MC-BLPT2U is a step-down switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 2.5V to 10V and provides a fixed output voltage of 3.0V. The device utilizes PWM control with a switching frequency of 300kHz. It is housed in a compact SC-74A (SOT-753) surface-mount package, suitable for space-constrained designs. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated PWM control architecture for efficient DC-DC conversion
• Fixed 3.0V output capability for stable power delivery
• Compact SC-74A (SOT-753) surface-mount packaging

Applications

• Battery-powered portable electronic devices
• Embedded systems requiring regulated 3.0V supply
• Industrial control modules with wide input voltage ranges

Procurement Notes

Verify the exact suffix 'BLPT2U' against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with external MOSFETs and passive components required for the buck topology. Confirm availability status as distribution data may vary.

Selection Notes

Select this component when a fixed 3.0V output is required from a 2.5V to 10V input source. The 300kHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the external switch current rating meets the application's load requirements.

Part Context

This part belongs to the S-8521 series of switching regulators from ABLIC. The series focuses on high-efficiency step-down conversion with integrated control logic. The specific model denotes the output voltage and package configuration within this product line.

Replacement Considerations

Check for direct pin-compatible substitutes within the S-8521 family or other ABLIC buck controllers. Verify that alternative parts match the 3.0V output and 300kHz switching frequency constraints.
