Each output is The PWR1546A has a maximum of 1mVp-p output noise. This unit regulated and is protected against all shorts. The isolation barrier incorporates input and output ltering along with an internal shield, is guaranteed to be 750VDC. giving full six-sided shielding that keeps unwanted radiated noise from your circuit. No external parts are required to meet the 1mVp-p Surface-mounted components and thermal encapsulant allow superior maximum guaranteed output noise. reliability and excellent thermal dissipation. The calculated MTTF (per MIL-HDBK-217 Rev. E, Circuit-Stress Analysis Method) is in excess The PWR1546A is a miniature DC/DC converter providing dual isolated of 100 years at 25C. 15VDC outputs from a single +5VDC input.
