S-19999BA-S8T1U7

Overview

The S-19999BA-S8T1U7 is a positive output step-up DC-DC controller IC manufactured by ABLIC Inc. It operates within an input voltage range up to 8.50 V and utilizes a switching frequency of 2.2 MHz. The component is housed in an 8-pin HTMSOP package, designed for surface-mount technology applications requiring compact power management solutions.

Feature Summary

• Functions as a boost regulator for positive output step-up DC-DC conversion
• Integrates a high-frequency switching controller for efficient power management

Applications

• Portable electronic devices requiring voltage step-up
• Battery-powered systems needing regulated higher voltage rails
• Compact consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet before procurement. Confirm availability through authorized distributors, as lead times may vary. Ensure compatibility with your system's thermal and electrical requirements prior to finalizing orders.

Selection Notes

Select this component when a fixed boost topology with a 2.2 MHz switching frequency is required. The 8.50 V input limit defines its operational boundary. Consider the HTMSOP-8 package dimensions for board space constraints. Validate that the external component selection aligns with the controller's internal compensation and timing specifications.

Part Context

This part belongs to ABLIC's series of DC-DC switching controllers. It complements other power management ICs by providing a dedicated solution for step-up voltage conversion. The integration of the controller simplifies design by reducing the need for external logic or complex driver circuits typically associated with discrete boost regulators.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify pinout and electrical characteristics carefully if considering alternative manufacturers' boost controllers.
