Overview
The A8480EEJTR-T is a DC-DC step-up regulator IC manufactured by Allegro MicroSystems, designed for display bias and LED driver applications. It operates within an input voltage range of 2.7V to 5.5V and delivers a regulated output current up to 1.5A. The device integrates a high-efficiency power switch and supports external inductor selection for flexible design. It functions with a switching frequency adjustable from 600kHz to 2.2MHz, allowing optimization for size and efficiency. The component is housed in a compact 10-TDFN package, suitable for space-constrained portable electronics.
Feature Summary
- Integrated high-efficiency power switch for boost regulation
- Adjustable switching frequency for design flexibility
- Compact surface-mount packaging for space-sensitive designs
Applications
- Display bias voltage generation
- LED driver circuits
- Portable electronic devices requiring step-up conversion
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 10-TDFN package dimensions match your PCB footprint requirements. Ensure the input voltage range aligns with your system's power supply characteristics before procurement.
Selection Notes
Select this component when a compact boost regulator is needed for LED or display bias applications. Consider the 1.5A output capability and adjustable frequency range against your efficiency and size constraints. Verify compatibility with your desired switching frequency setting components.
Part Context
This part belongs to Allegro's portfolio of power management integrated circuits (PMIC). It complements their broader range of motor drivers and sensor solutions, focusing on efficient power conversion for consumer and industrial electronics. The A8480 series addresses the need for small form-factor DC-DC converters.
Replacement Considerations
Check datasheets for alternative Allegro boost regulators like the A8483 if higher switching frequencies are required. Evaluate other manufacturers' 1.5A boost converters only if pinout and electrical specifications are fully compatible.
