Product details

Description

The LTC7891 is a high performance, 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.
