Datasheet Summary
Data Sheet LTC7891
100 V, Low IQ, Synchronous Step-Down Controller for GaN FETs
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 and UVLO
- Low operating IQ: 5 μA (48 VIN to 5 VOUT)
- Programmable frequency (100 kHz to 3 MHz)
- Phase lockable frequency (100 kHz to 3...
