S-8520C34MC-BRTT2G

Overview

The S-8520C34MC-BRTT2G is a CMOS step-down switching regulator controller from the S-8520 series, manufactured by ABLIC Inc. It utilizes Pulse Width Modulation (PWM) control to provide low-ripple power and high efficiency. The device operates within an input voltage range of 2.5V to 10V and supports a maximum switching frequency of 375kHz. It features a duty ratio capability varying linearly from 0% up to 100%. The component is housed in a SC-74A (SOT-753) package with five terminals.

Feature Summary

Integrates PWM control circuitry for linear duty ratio adjustment from 0% to 100%
Includes built-in error amplifier and soft-start circuit to prevent startup overshoot
Supports external Pch power MOS FET or PNP transistor configurations

Applications

Step-down DC-DC converter designs requiring low output ripple
Portable electronic devices utilizing battery power sources
Embedded systems requiring stable regulated voltage rails

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status prior to integration. Ensure design compatibility with specified operating temperature ranges. Review datasheet revisions for any marking or specification updates before finalizing procurement orders.

Selection Notes

Select this controller when precise PWM regulation is required over variable load conditions. Consider the 375kHz switching frequency for balancing component size and efficiency. Verify that the external power stage matches the controller's drive capabilities. Evaluate thermal performance requirements based on the specific application environment.
