JW3510 DC-DC isolated Flyback converter chip characteristics

        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

* 1.4A, 65V internal DMOS power switch

* Operating frequency up to 430KHz

* Low static current

* Boundary mode operation under overloaded conditions

* Burst mode operation under light load

* VOUT setup with single external resistor

* Minimum load < 0.5% of full output (typical value)

* No need for transformer third winding or photocoupler adjustment

* Internal compensation and soft start

* Input undervoltage lock

* Output short circuit protection
