The MTN-MAXlp HP is a high performance constant current LED buck (step down) driver, unparalleled in its output capability for size.  

This driver MUST be soldered into the pill or held in place with a retaining ring.  There must be a thermal connection between the driver and pill.  This means that you cannot simply piggyback or run the driver with only air cooling.  The driver WILL overheat if not properly connected to the host. 

Since the MTN-MAX is a step down driver, please ensure that your input voltage is greater than your output voltage. 

This driver takes up to 10 business days to be built, tested, and shipped.  Your order will not ship until the driver is completed.  

Features and Specifications:

• Low-profile: only 6mm tall on the LED side with Coilcraft inductor; ~4mm tall with standard inductor
  • Nearly flat on the battery side
• Mode level options (see below)
• 2S-4S input voltage range
• Designed primarily with a 3V LED in mind, such as the XM-L2, XP-G2, XP-L, Nichia 219/319, etc.
  • Can be used with a 6V LED such as the MT-G2 or XHP50/XHP70, but the maximum drive current is 4.5A.
  • Can be used with a 12V LED such as the XHP35, where the maximum drive current is 2.5A.
• Plenty of component clearance for retaining rings and a full ground ring for easy soldering
