17mm boost driver
This boost driver (input voltage is lower than output voltage) can drive 6V LEDs, such as the XHP50.2/70.2 from a single rechargeable lithium-ion battery at an output current of up to 4.2A. It can also drive a 12V LED, such as the XHP35, at up to around 1.3A. The MTN-BST2 uses a highly efficient synchronous boost converter squeezed into a tiny 17mm form factor.
Unlike most of the high power boost drivers out there, this driver can achieve a wide dimming range and utilize popular firmwares.
This driver takes up to 10 business days to be built, tested, and shipped. Your order will not ship until the driver is completed.
Battery & Host Requirements:
In stock form, this driver will pull just over 10A peak current, therefore a 10A+ continuous rated battery is required (unless you reduce the input current limit). The more voltage the battery can hold under load, the better the driver will perform. Your switch, springs, etc. must be able to handle the 10A+ input current; this means that you must have high performance or bypassed springs in your light.
The driver _must_ be soldered into the pill or held firmly in place with a retaining ring. This is required both for adequate thermal and electrical performance. If during use the light turns off and on, the driver is overheating and needs to be switched to a lower mode or turned off and allowed to cool. Continued operation at excessively high temperature will damage the driver (damage from excessive temperature will not be covered under warranty).
Boost Converter (input voltage must be lower than output voltage)
3V - 5.5V input voltage range (suitable for a single lithium-ion battery)
Designed to drive 6V LEDs, such as the XHP50.2 and XHP70.2 at drive currents up to 4.5A
Can also drive 12V LEDs, such as the XHP35 at currents up to around 1.3A
Output voltage range: ~6V —- ~13.8V
Output current range: 6V LED: 1A —- 4.2A
XHP50 / 50.2
XHP70 / 70.2
12V LED: ~1.3A
XHP35 HD / HI
Input Current Limit Option:
If you are running any battery that is not capable of 10A+ continuous discharge current, you must change the input current limit to a lower value.
~10.5A | 4.2A w/ 6V LED maximum recommended output current
~8A | 3.5A w/ 6V LED maximum recommended output currnet
~4A | 2A w/ 6V LED maximum recommended output current
Output Current Option:
The output current is set using one or two sense resistors. You can choose between any of the following output current limit options:
Currently only guppy3drv is available. We will have Bistro available as soon as we get it 100% dialed in.
