Description and Introduction

Automotive Catalog Current-Mode PWM Controller The UC2845AQD8R is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UC2845AQD8R  
- **Type:** Current-Mode PWM Controller  
- **Package:** SOIC-8  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Switching Frequency:** Up to 500 kHz  
- **Input Voltage (VCC):** 7.6V to 30V  
- **Output Current (Gate Drive):** 1A (Peak)  
- **Duty Cycle Range:** 0% to 100%

### **Descriptions:**  
The UC2845AQD8R is a fixed-frequency PWM controller optimized for high-performance DC-DC power supplies. It features current-mode control for improved loop response and includes built-in protections such as undervoltage lockout (UVLO), cycle-by-cycle current limiting, and a latch for single-pulse metering.  

### **Features:**  
- **Current-Mode Operation** for improved transient response  
- **Automatic Feed-Forward Compensation**  
- **Latching PWM** for cycle-by-cycle current limiting  
- **Internal Trimmed Bandgap Reference** (5V ±1%)  
- **High-Current Totem-Pole Output** (1A peak)  
- **Low Startup Current** (<1mA)  
- **Undervoltage Lockout (UVLO)** with hysteresis  
- **Compatible with Voltage-Mode Operation**  

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