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