### **Descriptions:**
The MAX16802BEUA+ is a synchronous buck (step-down) DC-DC converter designed for high-efficiency power conversion in applications requiring a compact footprint. It integrates high-side and low-side MOSFETs, reducing external component count. The device operates at a fixed 500kHz switching frequency, allowing for small external inductors and capacitors.
### **Features:**
- **Integrated Power MOSFETs** (High-side and low-side switches)
- **Adjustable Output Voltage** (via external resistor divider)
- **High Efficiency** (up to 95%)
- **Wide Input Voltage Range** (4.5V to 28V)
- **Fixed-Frequency Operation** (500kHz) for predictable EMI performance
- **Soft-Start Function** to limit inrush current
- **Thermal Shutdown Protection**
- **Overcurrent Protection**
- **Undervoltage Lockout (UVLO)** for safe operation
