S-8521D18MC-BXDT2G

Overview

The S-8521D18MC-BXDT2G is a step-down DC-DC switching controller manufactured by ABLIC Inc. It operates with a fixed switching frequency of 60kHz and supports a maximum duty cycle of 100%. The device features a positive output configuration and utilizes a transistor driver for its single output stage. It requires a supply voltage (Vcc/Vdd) ranging from 2.5V to 16V. The component is housed in an SC-74A or SOT-753 package, specifically SOT-23-5, and is designed for surface mount installation. It functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

Supports 100% maximum duty cycle operation
Includes enable control functionality
Utilizes transistor driver output type

Applications

General purpose step-down power conversion circuits
Embedded systems requiring regulated positive voltage rails
Industrial equipment power management modules

Procurement Notes

Verify the specific suffix 'BXDT2G' against official ABLIC documentation to confirm exact marking codes and tape-and-reel specifications. Ensure compatibility with the required 60kHz switching frequency and 16V maximum supply voltage limits for your target application design before finalizing procurement orders.

Selection Notes

Select this component when a fixed 60kHz switching frequency is preferred over variable options. It is suitable for designs requiring a 16V maximum input supply range and positive output regulation. Consider the SOT-23-5 package constraints and the absence of synchronous rectification if efficiency requirements differ significantly.

Part Context

This part belongs to the S-8521 series of buck switching controllers from ABLIC Inc. The series offers various output voltage configurations and switching frequencies. This specific model provides a fixed 60kHz operation point, distinguishing it from higher-frequency variants like the 180kHz S-8520 series.
