The JW®3510 is a micropower isolated Flyback converter. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no third winding or opto-isolator for regulation. The output voltage can be programmed with a single external resistor. Besides, internal compensation and soft-start further reduce external component count.

The JW3510 operates with an input voltage range of 3.0V to 48V and can deliver up to 7W of isolated output power. The primary-side can deliver 1.4A peak current with an internal integrated 75V N-Channel DMOS power switch. The JW3510 is designed with boundary mode, discontinuous mode and burst mode operation at different load to improve load regulation and maintain high efficiency while minimizing the output voltage ripple.

JW3510 is available in the SOT23-5 package. The high level of integration results in a simple to use, low component count, and high efficiency application solution for isolated power delivery.
