HXY4404 Mos Field Effect Transistor Low Gate Charge For Switching Application

Product Summary

General Description

The HXY4404 uses advanced trench technology to

provide excellent RDS(ON), low gate charge and operation

with gate voltages as low as 2.5V. This device makes an

excellent high side switch for notebook CPU core DC-DC

conversion.

Applications

High efficiency power supply

Secondary synchronus rectifier

Electrical Characteristics (T =25°C unless otherwise noted)

A. The value of R_θJA is measured with the device mounted on 1in² FR-4 board with 2oz. Copper, in a still air environment with T_A =25°C. The

value in any given application depends on the user's specific board design.

B. The power dissipation P_D is based on T_J(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance.

C. Repetitive rating, pulse width limited by junction temperature T_J(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep

initialT =25°C.

D. The R_θJA is the sum of the thermal impedance from junction to lead R_θJL and lead to ambient.

E. The static characteristics in Figures 1 to 6 are obtained using <300µs pulses, duty cycle 0.5% max.

F. These curves are based on the junction-to-ambient thermal impedance which is measured with the device mounted on 1in² FR-4 board with

2oz. Copper, assuming a maximum junction temperature of T_J(MAX)=150°C. The SOA curve provides a single pulse rating.

G. The spike duty cycle 5% max, limited by junction temperature TJ(MAX)=125°C.
