Overview
The A8430EEK is a single-output DC-DC boost LED driver IC manufactured by Allegro MicroSystems. It operates with an input supply voltage range of 2.5V to 10V and delivers a regulated output current of 20mA per channel. The device supports PWM dimming control and integrates an internal switch within a 5-MLPD (3x3) surface-mount package. It functions as a step-up converter capable of driving LEDs up to a 36V output voltage. The component is rated for an ambient operating temperature range of -40°C to 85°C.
Feature Summary
- Integrates an internal power switch for compact design
- Supports PWM dimming for brightness control
- Functions as a step-up DC-DC converter topology
Applications
- LED backlighting systems
Procurement Notes
Verify the specific ordering suffix 'EEK' against the manufacturer's official documentation, as suffixes often denote packaging variations or environmental compliance status rather than functional changes. Confirm RoHS compliance requirements, as this specific part number may not meet current RoHS standards according to distributor records. Check for active lifecycle status, as the product is listed as obsolete in some channels.
Selection Notes
Select this component when a single-channel, high-efficiency boost driver is required for low-current LED applications. Ensure the design accommodates the 5-MLPD package footprint and thermal dissipation needs. Verify that the input voltage range of 2.5V to 10V aligns with the system power supply. Consider the 1.2MHz switching frequency for inductor selection and EMI management.
Part Context
The A8430 belongs to Allegro MicroSystems' portfolio of LED driver integrated circuits designed for efficient light management. This series utilizes a boost topology to drive LEDs from lower input voltages. The A8430EEK specifically refers to the variant packaged in a 5-lead Molded Leadless Package (MLPD), suitable for space-constrained portable electronics and display backlights.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. As the A8430EEK is listed as obsolete, consult Allegro MicroSystems for current recommended replacements or equivalent products from other manufacturers.
