Most dc-dc converters require a soft-start circuit to limit the in-rush current at startup. Although a smooth soft start is required for systems with power-on reset (POR), this is difficult to ...
Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...
Designed specifically as a built-in power supply for ADSL fast-switching applications, the MB39A112 dc/dc converter is a three-channel converter that uses PWM to achieve oscillating frequencies ...
