Typ. Max. Units The NDY series is a range of low prole DC-DC All NDY05XX 4.5 5 9 converters offering a single regulated output over a All NDY12XX 9 12 18 2:1 input voltage range. All parts deliver 3W output Voltage range VDC All NDY24XX 18 24 36 power up to 85C without heatsinking, except the All NDY48XX 36 48 72 4.5V to 9V input voltage range which should be NDY2403 180 360 derated to 2W at the lower input voltage. A yback NDY4803 140 290 oscillator design with isolated feedback is used to All NDY05XX 400 500 give regulation over the full operating range of 25% 2 mA p-p Reected ripple current All NDY12XX 150 170 to 100% of full load. It is strongly recommended All other NDY24XX 290 360 that external capacitors be used on input and All other NDY48XX 100 127 output to guarantee performance over full load and input voltage range. 1. Refer to power derating graph. 2. Measured at full load with external input/output capacitors, refer to lter circuit 1. 3. Calculated using MIL-HDBK-217F with nominal input voltage at full load (ground benign) at 25C.
