The input voltage range is 2:1 with the output power at 2 watts and the input to output isolation is 1kVDC. Continuous short circuit protection, external control and extremely small SIP packaging provide state of the art functionality. The use of ceramic capacitors and a ceramic substrate, with a tough chip and wire bonded MOSFET power transistor die and SMD construction, provide genuine high reliability. Nominal input voltages of 5,12,24 and 48V with output voltages of 5,9,12 and 15V are available as standard with custom parts on request. The plastic case is rated to UL 94V-0 with encapsulant to UL 94V-1. Connection pins are phosphor bronze with a 60/40 tin lead solder dipped finish.
