PAM2861CBR-A

Overview

The PAM2861CBR-A is a continuous-mode inductive step-down LED driver IC manufactured by Diodes Incorporated. It features an integrated 40V NDMOS switch and supports a 1A output current. The device operates within a 6V to 40V input voltage range and utilizes a Buck topology. Key electrical parameters include an adjustable output voltage, a switching frequency between 233 kHz and 1 MHz, and a maximum supply current of 600 uA. It is housed in a SOT-89-5 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 40V NDMOS switch for compact design
• Supports PWM dimming for brightness control
• Includes open LED protection circuitry

Applications

• LED lighting drivers
• High power HBLED drivers
• General DC/DC converter applications

Procurement Notes

Verify the specific suffix 'A' against the official Diodes Incorporated datasheet to confirm if it denotes a specific tape-and-reel quantity or environmental compliance variant distinct from the standard PAM2861CBR. Ensure the ordering information matches the exact part number required for your bill of materials to avoid substitution errors.

Selection Notes

Select this component for applications requiring a single-channel buck LED driver with high input voltage tolerance up to 40V. It is suitable for designs needing internal switching capability to reduce external component count. Consider the SOT-89-5 package constraints and the 1A current limit when sizing thermal management solutions.
