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 full-rated current over the entire specifi cation range. Each output is incorporates input and output fi ltering along with an internal shield, regulated and is protected against all shorts. The isolation barrier giving full six-sided shielding that keeps unwanted radiated noise is guaranteed to be 750VDC. 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 The PWR1546A is a miniature DC/DC converter providing dual isolated MIL-HDBK-217 Rev. E, Circuit-Stress Analysis Method) is in excess ±15VDC outputs from a single +5VDC input. Each output will supply of 100 years at 25°C.

A IN LOAD 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 integ- rity 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 tem- perature limits. www.murata-ps.com/support MDC_PWR1546AC.C02 Page 3 of 4
