Integrated N-Channel PowerTrench MOSFET and Schottky Diode
General Description
Features
This device is designed specifically as a single package
MOSFET:
• 2.9 A, 30 V RDS(ON) = 123 mΩ @ VGS = 4.5 V
solution for a boost topology in cellular handset and
RDS(ON) = 140 mΩ @ VGS = 3.0 V
other ultra-portable applications. It features a MOSFET
RDS(ON) = 163 mΩ @ VGS = 2.5 V
with low input capacitance, total gate charge and onstate resistance, and an independently connected
schottky diode with low forward voltage and reverse
leakage current to maximize boost efficiency.
The MicroFET 2x2 package offers exceptional thermal
performance for its physical size and is well suited to
switching and linear mode applications.

1. RθJA is determined with the device mounted on a 1 in oz. copper pad on a 1.5 x 1.5 in. board of FR-4 material. RθJC is guaranteed by design while RθJA is
determined by the user's board design.
(a) MOSFET RθJA = 83°C/W when mounted on a 1in2 pad of 2 oz copper, 1.5” x 1.5” x 0.062” thick PCB
(b) MOSFET RθJA = 193°C/W when mounted on a minimum pad of 2 oz copper
(c) Schottky RθJA = 101°C/W when mounted on a 1in2 pad of 2 oz copper, 1.5” x 1.5” x 0.062” thick PCB
