Description and Introduction

Digital Control Compatible Synchronous Buck ±4-A Drivers with Current Sense Conditioning Amplifier The UCD7230RGW is a synchronous buck MOSFET driver manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range (VDD):** 4.5V to 15V  
- **Output Drive Voltage (VDRV):** 4.5V to 15V  
- **Peak Source Current:** 4A  
- **Peak Sink Current:** 4A  
- **Propagation Delay (Typical):** 20ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin VQFN (RGW)  

### **Descriptions:**
- The UCD7230RGW is a high-performance, dual-channel MOSFET driver designed for synchronous buck converters.  
- It provides strong gate drive capability with 4A source/sink current for fast switching of power MOSFETs.  
- It includes adaptive dead-time control to prevent shoot-through in synchronous buck topologies.  
- The device is compatible with PWM controllers and supports high-frequency switching applications.  

### **Features:**
- **Dual-Channel Driver:** Independently drives high-side and low-side MOSFETs.  
- **Adaptive Dead-Time Control:** Ensures efficient switching and prevents cross-conduction.  
- **Wide Input Voltage Range:** Supports 4.5V to 15V for flexibility in power supply design.  
- **High-Speed Switching:** Low propagation delay (20ns typical) for high-frequency operation.  
- **Integrated Bootstrap Diode:** Simplifies high-side gate drive circuitry.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  

This information is based on the manufacturer's datasheet for the UCD7230RGW.
