This board demonstrates an isolated, high-efficiency synchronous buck converter switch-mode
power supply (SMPS) using the world’s smallest isolators, NVE IsoLoop® MSOP Isolators.
The output is 3.3V at 750 mA.
The board has three channels of isolation to ensure the output is electrically isolated from the
input. A two-channel MSOP-8 isolator isolates synchronous rectification and a single-channel,
failsafe, MSOP-8 isolator isolates output-voltage feedback. MSOP isolators minimize board area.
Despite the compact components, the board has 1.2 kV isolation and maintains 3 mm creepage.

IL6xxCMTI-Series isolators are
optimized for driving MOSFETs either directly or with an
external gate driver.
Resistors set the input current, and five milliamps guarantees
switching. The inputs can be configured as non-inverting or
inverting.
CMTI-grade isolators are 100% tested to ensure each part has
at least 200 kV/µs minimum Common-Mode Transient
Immunity. Simple external deglitch circuitry can extend the
CMTI to an extraordinary 350 kV/µs typical.
The parts also have an extended supply range of up to 6.6 volts
for compatibility to directly drive a range of power
MOSFETs or gate driver ICs. The parts provide full 2.5 kV isolation.
The IL611CMTI-1E is a two-channel version in an ultramniature MSOP8 package.
