S-8533A60AFT-TB-U

Overview

The S-8533A60AFT-TB-U is a step-down synchronous PWM control switching regulator controller manufactured by ABLIC Inc. It operates within an ambient temperature range of -40°C to 85°C and utilizes an 8-TSSOP surface-mount package. The device supports positive output configuration and includes built-in current sensing with slope compensation to facilitate synchronous rectification at a switching frequency up to 300kHz.

Feature Summary

• Supports synchronous rectification via integrated current sensing and slope compensation
• Features enable and soft start control capabilities for regulated power management

Applications

• Board-level DC-DC conversion systems requiring buck topology
• Power management units in industrial or automotive environments operating between -40°C and 85°C

Procurement Notes

Verify the specific suffix 'TB-U' against official ABLIC documentation to confirm pinout and electrical characteristics, as ordering suffixes may alter functional parameters. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select this component when a synchronous buck controller with integrated current sensing is required. Ensure the application demands a switching frequency compatible with the 300kHz limit and fits within the specified thermal operating range. Validate that the 8-TSSOP package aligns with the target PCB layout constraints.
