LTC7890 - 2-Phase Synchronous Step-Down Controller

Description

The LTC7890 is a high performance, dual step-down, dc-to-dc switching regulator controller that drives all N-channel synchronous gallium nitride (GaN) field effect transistor (FET) power stages from input voltages up to 100 V.

Features

  • GaN drive technology fully optimized for GaN FETs.
  • Wide VIN range: 4 V to 100 V.
  • Wide output voltage range: 0.8 V ≤ VOUT ≤ 60 V.
  • No catch, clamp, or bootstrap diodes needed.
  • Internal smart bootstrap switches prevent overcharging of high- side driver supplies.
  • Internally optimized, smart near zero dead times or resistor adjustable dead times.
  • Split output gate drivers for adjustable turn on and turn off driver strengths.
  • Accurate adjustable driver voltage.
