Irvine-based mobile device accessories maker Incipio Technologies Inc. secured $55 million in financing from Monroe Capital LLC.

Incipio makes cellphone and tablet cases, as well as headphones, keyboards and other accessories. It had an estimated $200 million in sales in 2013.

Chief Executive Andy Fathollahi said the $55 million credit facility is expected to provide the company with “increased flexibility as we continue to grow, both organically and through acquisitions.”

Chicago-based Monroe Capital provides debt and equity investments to “middle market” companies in the U.S. and Canada. It looks for companies with minimum operating earnings of $3 million, according to its website.
