PWR1546AC www.murata-ps.com 5 Watts Regulated DC/DC Converters FEATURES 1mVp-p MAXIMUM OUTPUT NOISE 5W RATED OUTPUT POWER SHORT-CIRCUIT PROTECTION SIX-SIDED SHIELDING INTERNAL INPUT AND OUTPUT FILTERING FULLY REGULATED APPLICATIONS HIGH RESOLUTION DATA ACQUISTION PRECISION TEST EQUIPMENT HIGH GAIN AMPLIFIERS PRECISION INSTRUMENTATION 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, Circuit-Stress Analysis Method) is in excess of 100 years at 25°C.

SOLDERING INFORMATION The PWR1546AC device is intended for wave soldering or manual soldering. It is not designed or intended to withstand surface mount processes under any circumstances. The normal wave soldering process can be used with this device where it is subjected to a maximum wave temperature of 260°C for a period of no more than 10 seconds. Within the constraints of these time and temperature limits, the integrity of the device’s plastic body will not will not be compromised and internal temperatures within the converter will not exceed 175°C. Care should be exercised in controlling the manual soldering process within these same time and temperature limits. www.murata-ps.com/support MDC_PWR1546AC.C02 Page 3 of 4 PWR1546AC 5 Watts Regulated DC/DC Converters Murata Power Solutions, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1151 U.S.A.
