Description and Introduction

High Efficiency Linear Regulator The UC2834Q is a high-performance, fixed-frequency current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 8V to 35V  
- **Operating Frequency:** 500 kHz (fixed)  
- **Output Drive Current:** ±1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Current Sense Threshold:** 1V  
- **Error Amplifier Bandwidth:** 5 MHz  
- **Soft-Start Capability:** Yes  
- **Undervoltage Lockout (UVLO):** Yes  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SOIC (D)  

### **Descriptions:**  
The UC2834Q is designed for high-frequency switching power supply applications. It features current-mode control for improved loop response and simplified compensation. The device includes an onboard error amplifier, precision reference, and a high-current totem-pole output driver.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **500 kHz Operation:** Enables high power density designs.  
- **High-Current Output Driver:** Supports fast switching of power MOSFETs.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Wide Input Voltage Range:** Suitable for various power supply applications.  
- **Error Amplifier with High Bandwidth:** Supports tight voltage regulation.  

This information is based on TI's official documentation for the UC2834Q.
