TDK Corporation (TSE:6762) announces the introduction of the 20W rated TDK-Lambda PYD20 series of 2” x 1” footprint DC-DC converters. Capable of operating from an ultra-wide 18:1 input of 8.5 to 160Vdc, the converters are compatible with 12V, 24V, 48V, 72V and 110Vdc nominal system voltages. Applications include railroad rolling stock and trackside equipment, robotics, power generation and scientific research equipment.

These converters are available with 5V, 12V, 15V single and +/-12V, +/-15V and +/-24 dual outputs. The dual models can be configured to provide a 20W single 24V, 30V or 48V output. Using the trim function, they can be adjusted using a resistor or an external voltage to compensate for voltage drops, or to accommodate non-standard system voltages. The PYD20 models have overvoltage, overcurrent and overtemperature protection.

Remote on/off is also included as standard. Overall dimensions of the converters are 10.2mm high, 25.4mm wide and 50.8mm in length. The plastic case is silicone potted to provide a high resistance to shock and vibration. To meet demanding high voltage requirements for transients and a 5,000m altitude, the power modules have an input to output isolation of 3,000Vac. With efficiencies of up to 90%, power losses are minimized allowing the products to operate with case temperatures of up to -40°C to +105°C, with derating at high temperatures and convection or forced air cooling.

All models carry the CE and UKCA marks for the Low Voltage and RoHS Directives and are certified to the IEC/UL/CSA/EN 62368-1 safety standards. With external components the PYD20 series has been tested or designed to meet EN 50155 (railroad standard for electronic equipment in railroad vehicles), EN 45545-2 (fire safety) and EN 61373 (railroad vibration standard).

More information on the PYD20 series, including distributor inventory, can be obtained from the TDK-Lambda Americas website at https://www.us.lambda.tdk.com.
