JW3510 DC-DC isolated Flyback converter chip characteristics

The JW3510 is a micropower isolated flyback converter. The device does not require a third winding or optical isolator for adjustment by isolating the output voltage directly from the primary side by sampling the reverse shock shape. The output voltage can be programmed with an external resistor. In addition, racemization and soft starting further reduce the number of external components.

First、 Features of Chip JW3510:

* 3.0V to 42V working input range
