Overview
The A8430EEKTR-T is a single-output DC-DC boost LED driver IC manufactured by Allegro MicroSystems. It operates with a supply voltage range of 2.5V to 10V and delivers a regulated output current of 20mA per channel. The device integrates an internal switch and supports PWM dimming control for backlight applications. It functions at a switching frequency of 1.2MHz and provides a maximum output voltage of 36V. The component is housed in a 5-MLPD (3x3mm) surface-mount package and is rated for an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrates an internal power switch within a compact footprint to minimize external component count.
- Supports precise PWM dimming control for adjustable backlight brightness regulation.
- Utilizes a boost topology to drive LEDs from low-voltage supply sources.
Applications
- Backlight drivers for portable electronic devices
- LED illumination systems requiring PWM dimming
- Low-voltage power management circuits
Procurement Notes
Verify the specific suffix 'EEKTR-T' against official Allegro documentation to confirm the tape-and-reel packaging configuration. Confirm RoHS3 compliance status, as datasheet records may vary by revision. Check for obsolescence notices or product change notifications regarding the 5-MLPD package before finalizing procurement plans.
Selection Notes
Select this component when a single-channel boost driver with integrated switching capability is required for low-current LED loads. Ensure the input voltage stays within the 2.5V to 10V range and that the application demands a 20mA output current. Verify thermal performance requirements align with the specified ambient temperature limits for the chosen enclosure.
Part Context
This part belongs to the A8430 family of LED drivers designed for efficient power conversion in space-constrained environments. It serves as a specialized solution for managing LED arrays where size and integration are critical constraints compared to discrete solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Allegro MicroSystems technical support for qualified alternatives if this discontinued item requires replacement.
