**N-Channel Dual Cool[TM] 33 PowerTrench[®] MOSFET 25 V, 40 A, 5.7 m** Ω 

## **Features** 

Dual Cool[TM] Top Side Cooling PQFN package 

Max rDS(on) = 5.7 mΩ at  VGS = 4.5 V, ID = 17 A 

State-of-the-art switching performance 

Lower output capacitance, gate resistance, and gate charge boost efficiency 

Shielded gate technology reduces switch node ringing and increases immunity to EMI and cross conduction 

RoHS Compliant 

## **General Description** 

This  N-Channel MOSFET has been designed specifically to improve the overall  efficiency  and to  minimize  switch node ringing  of  DC/DC  converters  using  either  synchronous  or conventional switching PWM controllers. It has been optimized for  low gate charge, low  rDS(on), fast switching speed and body diode reverse recovery performance. 

## **Applications** 

High side switching for high end computing 

High power density DC-DC synchronous buck converter

2. Pulse Test: Pulse Width < 300 μs, Duty cycle < 2.0%. 

3. EAS of 29 mJ is based on starting TJ = 25 °C, L = 1.2 mH, IAS = 7 A, VDD = 23 V, VGS = 10V. 100% tested at L = 0.1 mH, IAS = 16 A. 

4. As an N-ch device, the negative Vgs rating is for low duty cycle pulse occurrence only. No continuous rating is implied. 

5. The continuous Vds rating is 25V; however, a pulse of 28 V peak voltage for no longer than 3ns duration at 500KHz frequency can be applied.
