TDK CORP. TDK-Lambda PYQ50 series of 30 to 75W rated quarter brick footprint dc-dc converters are capable of operating from an ultra-wide 12:1 input of 14 to 160Vdc (PYQ50) or 8:1 input 9 to 75Vdc (PYQ750. Devices 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. Products are available with 5V, 12V, 24V and 48V outputs and the PYQ75 with 12V, 15V, 24V, 28V and 48V. Using the trim function, devices can be adjusted using a resistor or an external voltage to compensate for voltage drops, or to accommodate non-standard system voltages. The PYQ models have overvoltage, overcurrent and overtemperature protection.
