30V N-Channel PowerTrench® MOSFET
General Description
This N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. It has been optimized for “low side” synchronous rectifier operation, providing an extremely low RDS(ON) in a small package.
Features
• 14 A, 30 V. RDS(ON) = 7.5 mΩ @ VGS = 10 V RDS(ON) = 9.0 mΩ @ VGS = 4.5 V
• Low gate charge (22 nC typical) • High performance trench technology for extremely low RDS(ON) • High power and current handling capability
Applications
• DC/DC converter

Notes: 1. RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RθJC is guaranteed by design while RθCA is determined by the user's board design.
