Description and Introduction

Fully Programmable Digital Power Controller with up to Two Regulated Outputs and Six DPWM Outputs The UCD3020 is a digital power controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 3.3V to 3.6V (digital core)  
- **Analog Supply Voltage:** 3.0V to 3.6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Control Method:** Digital PWM with adaptive dead-time control  
- **Resolution:** 7-bit for DPWM, 10-bit for ADC  
- **Communication Interface:** PMBus/I²C  
- **Package:** 48-pin QFN  

### **Descriptions:**  
The UCD3020 is a fully programmable digital PWM controller designed for high-performance power supply applications. It integrates a high-speed digital control loop, allowing precise regulation of power converters. The device supports multiple feedback loops, fault protection, and real-time monitoring via PMBus/I²C.  

### **Features:**  
- **Digital Control Loop:** Supports voltage, current, and temperature monitoring.  
- **Adaptive Dead-Time Control:** Optimizes efficiency by adjusting dead time dynamically.  
- **Programmable PWM Outputs:** Configurable for various topologies (buck, boost, etc.).  
- **High-Resolution ADC:** 10-bit ADC for accurate feedback sensing.  
- **Fault Protection:** Overvoltage, undervoltage, overcurrent, and overtemperature protection.  
- **Non-Volatile Memory:** Stores configuration settings.  
- **Flexible Synchronization:** Supports external clock synchronization.
