AL8807BMP-13

Overview

The AL8807BMP-13 is a PWM dimmable buck LED driver from Diodes Incorporated, housed in an 8-pin MSOP package with an exposed pad. It operates on a DC input voltage range of 6V to 36V and delivers a maximum output current of 1.3A. The device features a switching frequency of 1MHz and supports a maximum output voltage of 40V. It functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates a power MOSFET for compact circuit design
• Supports pulse-width modulation (PWM) dimming control
• Utilizes hysteretic control architecture for stable regulation

Applications

• 12V LED lighting systems
• 24V LED lighting systems
• MR16 LED lamps

Procurement Notes

Verify the specific suffix 'MP-13' against official Diodes Incorporated documentation to confirm pinout compatibility and thermal pad requirements. Confirm that the 8-MSOP-EP package matches the target PCB footprint. Ensure the application input voltage remains within the specified 6V to 36V range to prevent device malfunction or damage.

Selection Notes

Select this component for applications requiring high-frequency operation to minimize external passive component size. The integrated power switch simplifies bill of materials compared to discrete solutions. Verify that the required LED string forward voltage allows for proper headroom relative to the input supply voltage for efficient buck conversion.

Part Context

This part belongs to the AL8807 series of step-down DC/DC converters designed specifically for constant current LED driving. The series is engineered to reduce component count and printed circuit board area in low-voltage LED illumination projects. It serves as a specialized solution for replacing generic linear regulators or complex switching topologies in fixed-voltage LED arrays.
