Version 1.1 June 2015

Example 1

SPROG 3 (or SPROG II) driving multiple SBOOST II with common power
supply.

The power supply must be able to supply the full rated current (e.g., at least 5
Amp for 2 x SBOOST II).

Power districts must be separated by isolation gaps in both rails.

The SPROG 3 (or SPROG II) can be powered from one of the SBOOST II

Isolation Gap

Power

To further SBOOST
