Description and Introduction

Current-Mode PWM Controller The TL2845DR is a pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Input Voltage (VCC):** 8.5V to 30V  
- **Switching Frequency:** Up to 500 kHz  
- **Output Current (Gate Drive):** 1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SOIC-8 (DR package)  

### **Descriptions:**
The TL2845DR is a high-performance current-mode PWM controller designed for DC-DC converter and power supply applications. It features precise duty cycle control, cycle-by-cycle current limiting, and high noise immunity.  

### **Features:**
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.  
- **Programmable Oscillator:** Allows adjustable switching frequency via external components.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Error Amplifier:** Provides high gain-bandwidth for accurate regulation.  
- **Synchronous Operation:** Can be synchronized to an external clock.  
- **Low Standby Current:** Enhances efficiency in light-load conditions.
