Dual Output BST Models www.murata-ps.com Low-Cost, High Reliability 3 Watt, DC/DC Converters Typical units FEATURES PRODUCT OVERVIEW n Lowest cost! Highest reliability! n 100% SMT-on-pcb, including magnetics Rarely, has a Series of low-power DC/DC converters been defined by both low cost and Murata’s quality and reliability. Our new BST Series of dual-output 3W DC/DC’s achieves this “best-of-both-worlds” status by implementing a proven circuit architecture (170-200kHz flyback design) as a full, SMT-on-pcb assembly (including surface-mount magnetics) that is truly 100% automatically assembled. Packaged in miniature 1.25" x 0.8", DIP-like plastic packages (UL94V-0 rated) and requiring no external components, BST Series DC/DC’s bring true component-like convenience to designers of today’s distributed power systems. Output voltages are ±5, ±12 or ±15 Volts. Input voltage ranges are 4.5-9V (“D5” models), 9-18V (“D12” models) or an ultra-wide 18-72V (“D48” models). BST DC/DC’s are fully isolated (1000Vdc guaranteed) and include input (pi type) and output filters within their package. Output transient response n 100% automatically assembled n Standard "DIP" package and pinouts n Fully isolated, 1000Vdc guaranteed n ±5, ±12 or ±15 Volt outputs n Choice of 3 wide-range inputs: 4.5-9 Volts 9-18 Volts 18-72 Volts n Guaranteed efficiencies to 75% n–40 to +75°C full-power operation n Internal input/output filtering n UL1950/C22.2 No. 950/IEC950-1 certified is a quick 200µsec, while output ripple and noise are typically 75mVp-p. These rugged modules are fully encapsulated with a thermally conductive potting compound that contributes to their outstanding moisture/vibration resistance and impressive MTBF. They operate over the full –40 to +75°C temperature range without derating. All models have been thoroughly characterized (electrically, mechanically and thermally), qualified (including HALT), and EMI/EMC tested. Additionally, they are certified to UL1950, CSA 22.2 No. 950 and IEC950. Murata’s BST Model 3W DC/DC’s are excellent selections for telecom/datacom, computer and process-control applications demanding small size, low cost and high reliability. If required, their design “flexibility” allows for easy modification to your application-specific requirements. +VOUT +VIN COMMON –VOUT –VIN PWM CONTROLLER OPTO ISOLATION REFERENCE & ERROR AMP Typical topology is shown.
