Overview
The PAM2804AAB010 is a high-efficiency step-down constant current LED driver manufactured by Diodes Incorporated. It operates within an input voltage range of 2.5 V to 6 V and delivers a regulated output current of 1 A. The device integrates a 1.8 MHz switching frequency to minimize external component size. It features a buck topology that transitions into LDO mode when the input voltage falls below the LED forward voltage, ensuring stable operation across varying supply conditions.
Feature Summary
- Integrates step-down constant current regulation with automatic transition to LDO mode for low input voltages
- Utilizes a high 1.8 MHz switching frequency to reduce passive component footprint
- Supports dimming control capabilities for brightness adjustment
Applications
- Battery-powered portable lighting devices
- Low-voltage LED illumination systems
- Compact automotive interior lighting applications
Procurement Notes
Verify the specific suffix AAAB010 against the manufacturer datasheet to confirm pinout and packaging details. Ensure the TSOT-25 package variant matches your PCB layout requirements. Cross-reference the 1A current rating and 6V maximum input limit with your system design constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring a single-channel 1A drive from a 2.5V to 6V source. The integrated LDO mode provides flexibility for battery discharge curves. Consider the thermal performance in the TSOT-25 package under continuous 1A load conditions relative to your ambient temperature expectations.
Part Context
This part belongs to the PAM2804 series of LED drivers from Diodes Incorporated. It is designed as a compact solution for driving single-segment LED loads. The series focuses on efficiency and minimal external component count, targeting space-constrained consumer and industrial lighting applications.
Replacement Considerations
