A8498SLJ-T

Overview

The A8498SLJ-T is a high-voltage step-down regulator from Allegro MicroSystems, designed for applications requiring a wide input voltage range of 8 V to 50 V. It delivers an adjustable output voltage between 0.8 V and 24 V with a maximum output current of 3 A. The device features an integrated DMOS switch and supports a fixed off-time topology. It operates within a temperature range of -20 °C to +85 °C and is housed in an 8-pin SOIC package.

Feature Summary

Integrates a high-voltage DMOS power switch to simplify external component requirements.
Supports a wide input voltage range suitable for various industrial power sources.
Features adjustable fixed off-time control for stable switching performance.

Applications

Industrial automation power supplies
Automotive electronics systems
General-purpose DC-DC conversion

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and thermal characteristics. Ensure the selected variant matches the required operating temperature range and packaging style for your design. Cross-reference manufacturer part numbers to avoid confusion with similar series components.

Selection Notes

Select this component when a wide input voltage range up to 50 V is required alongside a 3 A output capability. Consider the integrated switch and fixed off-time architecture for simplified design. Verify that the SOIC-8 package fits the available PCB space and thermal management strategy.

Part Context

This part belongs to the A8498 series of high-voltage step-down regulators. It is distinct from motor driver variants like the A498x series or other PMICs such as the A8483. The series focuses on efficient power conversion for industrial and automotive loads.
