Operating Information Output Voltage Adjust (V ) adj All PMB 8000 Series DC/DC regulators have an Output Voltage adjust pin (Vadj). This pin can be used to adjust the output voltage above output voltage initial setting (0.75 V). When increasing the output voltage the maximum power rating of the converter remains the same, and the output current capability will therefore decrease correspondingly. To increase the output voltage a resistor or a voltage signal should be connected/applied between Vadj pin and GND, pin 5. The resistor/voltage signal value for some standard output trims are given below, for other voltage set points use the formulas to calculate the correct resistor or voltage signal. For output voltages of 5.25 V and higher the input voltage is restricted to maximum 14 Vin. Formula 1: Radj = (10 500 / (Vout – 0.7525)) – 1000 (ohm) Formula 2: Vtrim = (0.7 – 0.0667 x (Vout – 0.7525)) (V) Vout (V) Radj (kohm) 0.75 Open 1.0 41.42 1.2 22.46 1.5 13.05 1.8 9.024 2.5 5.009 ...

Operating Information Remote Sense All PMB 8000 Series DC/DC regulators have a positive re- mote sense pin that can be used to compensate for moder- ate amounts of resistance in the distribution system and al- low for voltage regulation at the load or other selected point. The remote sense line will carry very little current and does not need a large cross sectional area. However, the sense line on the PCB should be located close to a ground trace or ground plane. The remote sense circuitry will compensate for up to 10% voltage drop between the sense voltage and the voltage at the output pins from V nom. If the remote sense is O not needed the sense pin should be left open or connected to the positive output. Current Limit Protection The PMB 8000 Series DC/DC regulators include current limiting circuitry that allows them to withstand continuous overloads or short circuit conditions on the output. The out- put voltage will decrease towards zero for output currents in excess of max output current (Iomax). When the current limit is reached the regulator will go into hiccup mode. The cur- rent limit is temperature dependent, i.e. the limit decrease at higher operating temperature, the regulator is guaranteed to start at I max x 1.25 @ Tref 115°C. The regulator will O resume normal operation after removal of the overload. The load distribution system should be designed to carry the maximum output short circuit current specified. Over Temperature Protection (OTP) The PMB 8000 Series DC/DC regulators are protected from ...

The PMB 8000 series regulator can accept up to 8mF of capacitive load on the output at full load. This gives <500 mF When using that large capacitance it is important O to consider the selection of output capacitors; the resulting behavior is a combination of the amount of capacitance and ESR. A combination of low ESR and output capacitance exceeding 8mF for PMB 8818 can cause the regulator into over current protection mode (hick-up) due to high start up current. The output filter must therefore be designed without exceeding the above stated capacitance levels if the ESR is lower then 30-40 mΩ. Parallel Operation The PMB 8000 Series DC/DC regulators can be connected in parallel with a common input. Paralleling is accomplished by connecting the output voltage pins directly and using a load sharing device on the input. Layout considerations should be made to avoid load imbalance. For more details on paralleling, please consult your local applications support. Thermal Considerations General The PMB 8000 Series DC/DC regulators are designed to operate in a variety of thermal environments, however sufficient cooling should be provided to help ensure reliable operation. Heat is removed by conduction, convection and radiation to the surrounding environment. Increased airflow enhances the heat transfer via convection. Proper cooling can be verified by measuring the temperature at the reference point (T ). ref T ref 1 ...

Soldering Information The PMB 8000 series DC/DC regulators are intended for manual or wave soldering. The plastic body of the pin connectors resists soldering heat for limited time up to 260 °C. When hand soldering, care should be taken to avoid direct contact between the hot soldering iron tip and the pins for more than a few seconds in order to avoid melting of the plastic. Delivery Package Information The PMB 8000 series regulators are delivered in antistatic trays with Jedec standard outer dimensions. Tray capacity 25 pcs. Each box contains 4 full trays and one empty that functions as a lid. Compatibility with RoHS requirements The products are compatible with the relevant clauses and requirements of the RoHS directive 2002/95/EC and have a maximum concentration value of 0.1% by weight in homogeneous materials for lead, mercury, hexavalent chromium, PBB and PBDE and of 0.01% by weight in homogeneous materials for cadmium. Exemptions in the RoHS directive utilized in Ericsson Power Modules products include: • Lead in high melting temperature type solder (used to Lead in high melting temperature type solder (used to solder the die in semiconductor packages) ...
