Quarter brick dc-dc converters deliver 200-425Vdc input

TDK-LAMBDA PH-A280 series of dc-dc power modules with high voltage dc input operate from a wide range dc input of 200 to 425Vdc. Products are available in four output power levels of 50W, 75W, 100W and 150W, while nominal output voltages consist of 5V, 12V, 24V or 48Vdc. Devices are adjustable by -20% to +10% (+/-20% for 5V output models) and efficiencies of up to 90% are achieved.
