### **Descriptions:**
- The TPS62007DGS is a high-efficiency synchronous step-down converter optimized for low-power applications.
- It operates in PWM mode under moderate to heavy loads and automatically switches to power-save mode (PFM) at light loads for improved efficiency.
- The device integrates low RDS(on) MOSFETs to minimize power loss.
- It is designed for battery-powered portable devices, such as smartphones, tablets, and wireless modules.
### **Features:**
- **High Efficiency:** Up to 95% efficiency due to synchronous rectification.
- **Low Quiescent Current:** 17µA (typical) for extended battery life.
- **Adjustable Output Voltage:** Set via an external resistor divider.
- **100% Duty Cycle Mode:** Allows operation at very low input voltages.
- **Power-Save Mode (PFM):** Enhances efficiency at light loads.
- **Internal Soft-Start:** Reduces inrush current during startup.
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.
- **Thermal Shutdown:** Protects the device from overheating.
