Housed in DATEL’s standard 2" x 3" x 0.5" metal packages, these BMP duals can simultaneously source up to 4.7 Amps from their 5V outputs and up to 3.5 Amps from their 3.3V outputs. Both outputs are fully isolated (1500Vdc) and independently line (±1.0%) and load (±1.0%) regulated. Both models feature input pi filters, input overvoltage shutdown, input reverse polarity pro- tection, output overvoltage protection, output current limiting, and thermal shutdown. Both outputs are controlled via the On/Off Control function (pin 5). The 5 Volt output can be adjusted ±5%. BMP Model DC/DC’s deliver high efficiency (82%) and are fully specified for –40 to +100°C operation. Their corrosion-resistant metal cases have non-conductive baseplates and threaded inserts for easy heat-sink attachment and/or PCB mounting. These devices satisfy IEC950, UL1950 and EN60950 safety requirements for BASIC insulation. CE marking is available for "D48" models.

Fusing recommended. 6.8 Volts Output Current Current limited. Maximum current and short-circuit duration are model dependent. Storage Temperature –40 to +105°C These are stress ratings. Exposure of devices to greater than any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifications Table is not implied or recommended. Soldering Guidelines Murata Power Solutions recommends the specifications below when installing these converters. These specifications vary depending on the solder type. Exceeding these specifications may cause damage to the product. Be cautious when there is high atmospheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your production environment may differ; therefore please thoroughly review these guidelines with your process engineers.

As shown in Figure 6, the control pin has an internal 10kΩ pull-up resistor to approximately 10V. The converter is designed so that it is enabled when the control pin is left open (normal mode) and disabled when the control pin is pulled low (to less than +1.2V relative to –Input, pin 2). 5 ON/OFF CONTROL 2 –INPUT Dynamic control of the on/off function is best accomplished with a mechanical relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). The drive circuit should obviously be able to sink approximately 1.5mA when activated and withstand more than 10 Volts when deactivated. Applying an external voltage to pin 5 when no input power is applied to the converter can cause permanent damage to the converter. The on/off control function, however, is designed such that the converter can be disabled (pin 5 pulled low) while input power is ramping up and then "released" once the input has stabilized. Under these circumstances, it takes approximately 30ms for the output of the fully loaded DC/DC to ramp up and settle to within ±1% of its fi nal value after the converter has been turned on.

The trimpot should be connected as shown in Figure 3 with its wiper connected to pin 10 (Trim). A trimpot can also be used to determine the value of a single fi xed resistor which can be connected between pin 10 (Trim) and pin 9 (+5V Output) to trim "down" the output voltages, or between pins 10 (Trim) and 8 (Output Return) to trim "up" the output voltages. Fixed resistors should have absolute TCR's less than 100ppm/°C to ensure stability. 7 +3.3V OUTPUT 3 7 +3.3V LOAD +INPUT OUTPUT RETURN 8 RTRIM DOWN 2 TRIM –INPUT +5V OUTPUT +5V LOAD 10 9 Case Connection Unlike most other DC/DC converters, BMP DC/DC's do not have their metal case connected to one of their input pins.
