- 1A MOSFET gate driver
- 90μA typical start-up current, 125μA maximum
- 35ns propagation delay current sense to output
- Fast transient response with peak current-mode control
- 9V to 13.2V operation
- Adjustable switching frequency to 1MHz
- 50ns rise and fall times with 1nF output load
- Trimmed timing capacitor discharge current for accurate dead time/maximum duty cycle control
- 1.5MHz bandwidth error amplifier
- Tight tolerance voltage reference over line, load, and temperature
- ±3% current limit threshold
- Pb-free available (RoHS compliant)
- Radiation environment:
- High dose rate (50 - 300rad(Si)/s): 100krad(Si)
