DESCRIPTION

The PWR1546A has a maximum of 1mVp-p output noise. This unit

incorporates input and output ﬁ ltering 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

±15V

DC outputs from a single +5VDC input. Each output will supply

full-rated current over the entire speciﬁ cation 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, Circuit-Stress Analysis Method) is in excess

of 100 years at 25°C.
