S-8520D30MC-BVPT2G

Overview

The S-8520D30MC-BVPT2G is a CMOS step-down switching regulator controller from the ABLIC S-8520 series. It utilizes Pulse Width Modulation (PWM) control to provide low-ripple power and high efficiency. The device operates with an input voltage range of 2.5 V to 10 V and features a fixed output voltage setting of 3.0 V. It includes an internal error amplifier, oscillation circuit, and soft-start function to prevent startup overshoot. The component is housed in a compact SOT-23-5 package and supports surface mount installation.

Feature Summary

• PWM control circuit enables linear duty ratio variation from 0% to 100% for stable regulation
• Integrated soft-start circuit prevents output voltage overshoot during initial power-up
• Built-in error amplifier and reference voltage source ensure precise output stability

Applications

• Portable electronic devices requiring efficient step-down conversion
• Battery-powered equipment utilizing lithium-ion or lithium polymer cells
• Embedded systems needing stable low-voltage power rails

Procurement Notes

Verify the specific suffix BVPT2G against official ABLIC documentation to confirm pinout and marking codes. Ensure compatibility with external P-channel MOSFETs or PNPs as this is a controller IC. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement specifications.

Selection Notes

Select this component when PWM control is preferred over PFM for applications demanding minimal output ripple. Verify that the required output voltage matches the fixed 3.0 V setting or check if adjustable variants are needed. Ensure the external components selected can handle the maximum input voltage of 10 V and support the required load current for the target application.

Part Context

This part belongs to the S-8520/8521 series of switching regulator controllers designed for high-efficiency DC-DC conversion. The S-8520 series specifically focuses on PWM control, distinguishing it from the S-8521 series which supports both PWM and PFM modes. These controllers require external power switches and passive components to complete the buck converter topology.
