MAX783These codes are compatible with many popular PCMCIAdigital controllers such as the Intel 82365SL. For otherinterfaces, one of the inputs can be

+5V Inductor (L1)Three inductor parameters are required: the inductancevalue (L), the peak inductor current (ILPEAK), and thecoil resistance (RL). T

MAX783Ensure the transformer secondary is connected with theright polarity: A VDD supply will be generated with eitherpolarity, but proper operation

Diode D3The voltage rating of D3 should be at least 4 x VIN+5V plus a safety margin. A rating of at least 100V isnecessary for the maximum 20V supply

MAX783_______________Detailed DescriptionThe MAX783 converts a 5.5V to 30V input to six outputs(Figure 1). It produces two high-power, PWM switch-mode

zero (in discontinuous mode). Under fault conditionswhen the inductor current exceeds the 100mV current-limit threshold, the high-side latch resets an
