Description and Introduction

Low Input (2.25V-5.5V) 300 kHz Frequency, Synchronous Buck Controller, Source/ Sink, Prebias Operati The TPS40007DGQR is a synchronous buck controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.7V to 5.5V (adjustable)  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Pin MSOP (DGQ)  
- **Control Method:** Voltage Mode PWM  
- **Duty Cycle Range:** 0% to 100%  
- **Maximum Output Current:** Dependent on external components  

### **Descriptions:**
- The TPS40007DGQR is a high-efficiency synchronous buck controller designed for step-down DC-DC conversion.  
- It supports a wide input voltage range, making it suitable for various power supply applications.  
- The device includes adjustable switching frequency and soft-start functionality.  
- It is optimized for low-power applications with high efficiency and minimal external components.  

### **Features:**
- **Adjustable Output Voltage:** Uses an external resistor divider.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Programmable Soft-Start:** Prevents inrush current at startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage limits.  
- **Power Good (PG) Output:** Monitors output voltage status.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **External Compensation:** Allows flexibility in loop response tuning.  

This information is based solely on the manufacturer's datasheet and technical documentation.
