PLEASE EXPECT MUCH LONGER DELIVERY TIMES THAN NORMAL Shipping on a global scale is being affected by coronavirus measures, lockdown caused an increase on shipping and many shipping companies have exceeded their capacity to process the added load.

What is it?

TinyBoost 5V1A is a very small boost converter. It generates stable 5V1A power from a single cell lithium battery

What makes it special?

Using a 2.5MHz BGA boost converter chip (FAN48610) makes a difference. First of all.. its tiny! It operates with 2.5-4.8V input and delivers 5V1A. It offers soft start and short circuit protection and efficiency up to 94%. It can deliver up to 1.5A (with 4V+ input and added input/output capacitance).

It has been tested with 2 and 3 boards in parallel, soldered together with long header pins. This way higher currents are possible at a very small footprint, safely and without issues. A small switch can be connected onboard to enable/disable the converter or an external logic can do same.

You can order single converter or sets of 2 (for 2A output) and 3 (for 3A output).. Sets come with long header pins to attach the converters one on top of the other, thus paralleling them.
