RT8581AFN-B2B

Overview

The RT8581AFN-B2B is a high-output capability synchronous boost converter manufactured by Richtek Technology. It operates with an input voltage range of 2.7V to 12V and delivers a regulated output voltage between 4.5V and 12.6V. The device supports a maximum switch current (ISW) of 10A, enabling it to handle substantial power loads in compact designs. It utilizes a TSO package for surface-mount installation. The component features a quiescent current (Iq) of 30μA and is designed for efficient DC-DC conversion in space-constrained applications.

Feature Summary

High-output capability architecture supporting up to 10A switch current
Integrated bypass MOSFET functionality for enhanced efficiency
I²C control interface for programmable operation

Applications

Portable electronic devices requiring high current density
Battery-powered systems needing efficient voltage boosting
Compact consumer electronics with strict size constraints

Procurement Notes

Verify the specific suffix B2B against official Richtek documentation to confirm tape-and-reel specifications and marking codes. Ensure compatibility with I²C bus requirements and validate thermal performance within the TSO package limits for your specific PCB layout.

Selection Notes

Select this component when system design demands high output current exceeding standard boost converter capabilities while maintaining a small footprint. The integrated bypass feature and I²C control make it suitable for applications requiring dynamic power management and simplified compensation networks compared to traditional architectures.

Part Context

This part belongs to Richtek's portfolio of boost converters categorized by high-output capability. It complements other series like the RT4803 and RT4823, offering a distinct solution for applications prioritizing high current delivery over ultra-low quiescent current or bypass-specific low-voltage operations.
