Dual Output BST Models www.murata-ps.com Low-Cost, High Reliability 3 Watt, DC/DC Converters NOT RECOMMENDED FOR NEW DESIGNS Typical units FEATURES PRODUCT OVERVIEW Lowest cost Highest reliability Rarely, has a Series of low-power DC/DC converters is a quick 200sec, while output ripple and noise are been de ned by both low cost and Muratas quality typically 75mVp-p. 100% SMT-on-pcb, including magnetics and reliability. Our new BST Series of dual-output These rugged modules are fully encapsulated 100% automatically assembled 3W DC/DCs achieves this best-of-both-worlds with a thermally conductive potting compound that StandardDI package and pinouts status by implementing a proven circuit architecture contributes to their outstanding moisture/vibration (170-200kHz yback design) as a full, SMT-on-pcb resistance and impressive MTBF. They operate over Fully isolated, 1000Vdc guaranteed assembly (including surface-mount magnetics) that is the full 40 to +75C temperature range without der- 5, 12 or 15 Volt outputs truly 100% automatically assembled. Packaged in min- ating. All models have been thoroughly characterized Choice of 3 wide-range inputs: iature 1.25 x 0.8 , DIP-like plastic packages (UL94V-0 (electrically, mechanically and thermally), quali ed 4.5-9 Volts rated) and requiring no external components, BST (including HALT), and EMI/EMC tested. Additionally, 9-18 Volts Series DC/DCs bring true component-like convenience they are certi ed to UL1950, CSA 22.2 No. 950 and 18-72 Volts to designers of todays distributed power systems. IEC950. Guaranteed ef ciencies to 75% Output voltages are 5, 12 or 15 Volts. Input Muratas BST Model 3W DC/DCs are excellent voltage ranges are 4.5-9V (D5 models), 9-18V selections for telecom/datacom, computer and 40 to +75C full-power operation (D12 models) or an ultra-wide 18-72V (D48 process-control applications demanding small size, Internal input/output ltering models). BST DC/DCs are fully isolated (1000Vdc low cost and high reliability. If required, their design UL1950/C22.2 No. 950/IEC950-1 certi ed guaranteed) and include input (pi type) and output exibility allows for easy modi cation to your lters within their package.
