These power converters require a minimum output loading to maintain all specified regulations. Operation under no-load conditions will not damage these devices; however, they may not meet all the listed specifications. 2. All DC/DC converters should be externally fused at the front end for protection. *Due to advances in technology, specifications are subject to change without notice. 04/16/2012 Wall Industries, Inc. 5 Watson Brook Road Exeter, NH 03833 603-778-2300 www.wallindustries.com Fax 603-778-9797 Page 3 of 7 Rev.

B LANEUW Series Single and Dual Outputs 4:1 Ultra Wide Input Range 2 Watt DC/DC Power Converters TEST CONFIGURATIONS Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with an inductor Lin (4.7µH) and Cin (220µF, ESR < 1.0Ω at 100 KHz) to simulate source impedance. Capacitor Cin offsets possible battery impedance. Current ripple is measured at the input terminals of the module. Measurement bandwidth is 0-500 KHz. Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47µF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20MHz. Position the load between 50mm and 75mm from the DC/DC Converter. DESIGN & FEATURE CONSIDERATIONS Remote On/Off Negative logic remote on/off turns the module OFF during a logic high voltage on the remote on/off pin and ON during a logic low. To turn the module ON and OFF, the user must supply a switch to control the voltage between the on/off terminal and the –Vin terminal. The switch can be an open collector or equivalent. A logic high is 2.9V to 15V. A logic low is under 0.6VDC or open circuit, drops down to 0VDC by 2mV/°C. The maximum sink current at on/off terminal during a logic low is 1mA. The maximum allowable leakage current of the switch at on/off terminal = (under 0.6VDC or open circuit) is 1mA. Maximum Capacitive Load The LANEUW series has a limitation of maximum connected capacitance on the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the start-up time. The maximum capacitance can be found in the model selection tables. Over Current Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range. 04/16/2012 Wall Industries, Inc. 5 Watson Brook Road Exeter, NH 03833 603-778-2300 www.wallindustries.com Fax 603-778-9797 Page 5 of 7 Rev. B LANEUW Series Single and Dual Outputs 4:1 Ultra Wide Input Range 2 Watt DC/DC Power Converters Input Source Impedance The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor of 1.5µF for the 24V and 48V input devices. Output Ripple Reduction A good quality low ESR capacitor placed as close as possible across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 3.3µF capacitors at the output. Thermal Considerations Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module, and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 90°C. The derating curves are determined from measurements obtained in a test setup. 04/16/2012 Wall Industries, Inc. 5 Watson Brook Road Exeter, NH 03833 603-778-2300 www.wallindustries.com Fax 603-778-9797 Page 6 of 7 Rev.
