New Product

The DIODES™ Advantage

The APR34910 is a high-performance, cost-effective,

synchronous rectification solution for up to 65W

power in portable, consumer, and home automation

applications.

Secondary-

Side Synchronous Rectifier with Internal 10mΩ, 100V

N-Channel MOSFET Increases Efficiency in up to 65W Adaptors

The DIODES™ APR34910 is a low

secondary-side synchronous rectifier-

switcher used in power adaptors for

smartphones, laptops, and STBs.

With its low 10mΩ R

channel MOSFET, the APR34910

reduces secondary-side rectifier power

losses, increases efficiency, and

provides a high-performance solution.

The APR34910 supports continuous

conduction mode (CCM), discontinuous

conduction mode (DCM), and quasi-

resonant (QR) flyback operation.

Its short turn-on and turn-off delays

reduce power loss and eliminate false

triggering to keep safe operation without

adding any external components or

circuitry.

The APR34910 is internally charged by

a pulse linear regulator (PLR)

supporting operation with a voltage

output of 3.3V to 24V. This enables it to

support secondary voltage rails of 3.3V,

5V, 12V, and 20V as well as other non-

standard voltage rails.

The APR34910 is available in the SO-8

package with its drain pins all on one

side, which helps the device meet

creepage requirements.
