HIGH-EFFICIENCY, SOT23 STEP-DOWN, DC-DC CONVERTER The TPS62202DBV is a step-down DC-DC converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:
### **Specifications:**
- **Input Voltage Range:** 2.5V to 6V
- **Output Voltage Range:** Adjustable (0.7V to VIN) or fixed (0.7V, 1.2V, 1.5V, 1.8V, 1.85V, 2.5V, 3.3V)
- **Output Current:** Up to 300mA
- **Switching Frequency:** 1.25MHz (typical)
- **Efficiency:** Up to 95%
- **Quiescent Current:** 15µA (typical)
- **Operating Temperature Range:** -40°C to +85°C
- **Package:** SOT-23-5 (DBV)
### **Descriptions:**
The TPS62202DBV is a high-efficiency, low-quiescent-current synchronous step-down converter designed for battery-powered applications. It operates in pulse-frequency modulation (PFM) mode at light loads to improve efficiency and transitions to pulse-width modulation (PWM) mode at higher loads.
### **Features:**
- **High Efficiency:** Up to 95% due to synchronous rectification.
- **Low Quiescent Current:** 15µA (typical) for extended battery life.
- **Adjustable/Fixed Output Voltage:** Supports multiple fixed and adjustable output options.
- **1.25MHz Switching Frequency:** Allows for small external components.
- **100% Duty Cycle Mode:** Ensures operation at low input voltages.
- **Thermal Shutdown & Overcurrent Protection:** Built-in safety features.
- **Small Footprint:** SOT-23-5 package for space-constrained applications.
