Description and Introduction

High Speed Voltage Mode Pulse Width Modulator The part **UCC35705D** is manufactured by **Texas Instruments (TI)/Burr-Brown (BB)**. Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Category:** Integrated Circuits (ICs)  
- **Family:** Power Management (PMIC)  
- **Subcategory:** AC/DC Converters (Offline Switchers)  
- **Topology:** Flyback, Forward  
- **Control Mode:** Current Mode  
- **Switching Frequency:** Up to 1MHz  
- **Output Voltage:** Adjustable  
- **Input Voltage Range:** 8V to 14V (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package/Case:** SOIC-8  

### **Descriptions:**  
The **UCC35705D** is a high-performance current-mode PWM controller designed for offline power supplies. It is optimized for flyback and forward converter topologies, offering precise regulation and protection features. The device operates with a wide input voltage range and supports high-frequency switching for compact power supply designs.  

### **Features:**  
- **Current-Mode Control:** Ensures stable and efficient power conversion.  
- **Programmable Switching Frequency:** Up to 1MHz for flexible design.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Protects against low input voltage conditions.  
- **Over-Current Protection (OCP):** Safeguards against excessive load conditions.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **SOIC-8 Package:** Compact and suitable for space-constrained applications.  

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

### **Descriptions:**  
The **UCC35705D** is a high-performance current-mode PWM controller designed for offline power supply applications. It is optimized for flyback and forward converter topologies, providing precise regulation and efficient power conversion. The device features a fixed-frequency operation with a maximum switching frequency of 1MHz.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Programmable Switching Frequency:** Up to 1MHz for flexible design.  
- **Under-Voltage Lockout (UVLO):** Ensures reliable startup and shutdown.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **50% Duty Cycle Limitation:** Prevents transformer saturation.  
- **Low Operating Current:** Improves efficiency in standby mode.  
- **SOIC-8 Package:** Compact and suitable for space-constrained applications.
