S-19990CA-S8T1U7

Overview

The S-19990CA-S8T1U7 is a step-up and flyback switching regulator controller manufactured by ABLIC Inc. It utilizes high withstand voltage CMOS process technology and is housed in an 8-pin HTMSOP package. The device functions as a positive output DC-DC controller, supporting both boost and step-up/step-down topologies for efficient power conversion applications.

Feature Summary

• Integrated high withstand voltage CMOS design
• Supports step-up and flyback switching regulator topologies
• Positive output DC-DC control capability

Applications

• Step-up DC-DC converter circuits
• Flyback power supply designs
• Positive output voltage regulation systems

Procurement Notes

Verify the specific suffix S8T1U7 against the official ABLIC datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system requirements before ordering, as automotive or industrial variants may differ. Confirm RoHS compliance status directly with the manufacturer documentation.

Selection Notes

Select this component when designing circuits requiring integrated step-up or flyback control with high voltage tolerance. The CMOS process offers reliability benefits. Verify that the external components match the controller's drive capabilities and frequency requirements for stable operation.

Part Context

This part belongs to the S-19990 series of switching regulators from ABLIC. It is distinct from LDO regulators like the S-19212 series and monitor circuits like the S-19117 series. The series focuses on active switching control rather than linear regulation or voltage detection.
