### **Descriptions:**
- The ISL6612CB is designed to drive both high-side and low-side N-channel MOSFETs in synchronous buck converter applications.
- It integrates a high-speed level shifter for high-side gate driving and includes adaptive shoot-through protection to prevent cross-conduction.
- The driver is optimized for high-frequency switching applications, improving efficiency in DC-DC converters.
### **Features:**
- **Adaptive Shoot-Through Protection:** Prevents simultaneous conduction of high-side and low-side MOSFETs.
- **High-Speed Operation:** Fast propagation delays and rise/fall times for efficient switching.
- **Wide Operating Voltage Range:** Supports 4.5V to 13.2V supply for flexibility in power designs.
- **4A Peak Drive Current:** Ensures strong gate drive for fast switching transitions.
- **3.3V, 5V, and 12V Logic Compatible Inputs:** Works with various PWM controller outputs.
- **Undervoltage Lockout (UVLO):** Protects MOSFETs by disabling the driver if the supply voltage is too low.
The ISL6612CB is commonly used in voltage regulator modules (VRMs), DC-DC converters, and other power management applications.
