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.
