SI4728CY - N-Channel MOSFET

Description

The Si4728CY n-channel synchronous MOSFET with break-before-make (BBM) is a high speed driver designed to operate in high frequency dc-dc switchmode power supplies.

It’s purpose is to simplify the use of n-channel MOSFETs in high frequency buck regulators.

Features

  • D D D D 4.5- to 30-V Operation Driver Impedance.
  • 3 W Undervoltage Lockout Fast Switching Times (30 ns typ. ) D D D D 30-V MOSFETs High Side: 0.018 W @ VDD = 4.5 V Low Side: 0.0105 W @ VDD = 4.5 V Switching Frequency: 250 kHz to 1 MHz.
