This LAN C series is specially designed to provide 40mA output ripple, continuous short circuit protection, and up to 3 watts output power in a low-profile 24 pin DIP package. The -25°C to +71°C operating temperature range makes these converters ideal for data communication equipment, distributed power systems, telecommunication equipment, mixed analog/digital subsystems, industrial robot systems, and automatic test instrumentation. All models are 100% burned-in. SPECIFICATIONS: LAN C Series All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted. We reserve the right to change specifications based on technological advances.

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. A 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 100KHz) capacitor of a 2.2μF for the 5V input models, a 1.0μF for the 12V input models, and a 0.47μF for the 24V and 48V input models. +Vin + + DC Power Source +Out DC / DC Converter Load Cin -Vin - -Out Maximum Capacitive Load The LAN C Series has a limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time. For optimum performance we recommend 220μF maximum capacitive load for dual output models and 470μF capacitive load for single output models. The maximum capacitance can be found in the Output Voltage / Current Rating Chart. 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 100KHz) to simulate source impedance.

Current ripple is measured at the input terminals of the module. Measurement bandwidth is 0 ~ 500KHz. Peak-to-Peak Output Noise Measurement Test Use a Cout 0.33μF ceramic capacitor. Scope measurement should be made by using a BNC socket; measurement bandwidth is 0 ~ 20MHz.

To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 85°C.
