The Engineering Benchmark: True Current-Regulated Power in a Compact 7-Pin SIP
The BuckPuck 3021D Buck Driver with 7-pin SIP is a high-efficiency line of true current-regulated LED drivers available in both AC and DC input configurations that utilize buck topology to deliver constant outputs ranging from 350mA to 1000mA. These compact modules are designed to power high-brightness LED arrays without the need for external current-limiting resistors or additional heat sinking by varying the output voltage to maintain a specific current. Additionally, the line supports versatile integration with features such as 0–10V dimming, TTL/CMOS logic-level control, and fast response times suitable for flashing or strobe applications
