N-Channel MOSFET Ideal for Synchronous Buck Converters

 PDF

SUNNYVALE, Calif., – Alpha and Omega Semiconductor Limited (AOS) introduced AONE36132, a 25V N-Channel MOSFET in a dual DFN 3.3x3.3 packagewhich is ideal for synchronous buck converters. The AONE36132 is an extension to the XSPairFET lineup.  Designed with the latest bottom source packaging technology, the AONE36132 has lower switch node ringing due to lower parasitic inductance. This new XSPairFET offers a higher power density compared to existing solutions and is ideally suited for computing, server and telecommunication markets.

AONE36132 has an integrated high-side and low-side MOSFETs (7mOhms and 2mOhms maximum on-resistance, respectively) within a DFN 3.3x3.3 XSPairFET package.  The low-side MOSFET source is connected directly to the exposed pad on PCB to enhance thermal dissipation.  Using an existing notebook design under typical conditions, 19V input Voltage, with 1.05V output Voltage, and a 21A output load condition, the AONE36132 had more than a two percent efficiency improvement when compared to a single DFN 5x6 high side and single DFN 5x6 low side configuration.

Technical Highlights

The new product family offers various RDS(ON) levels in combination with multiple package options.

Pricing and Availability

The AONE36132 is immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 1,000 pieces is $0.91.
