Description and Introduction

BiCMOS Advanced Phase Shift PWM Controller 20-TSSOP 0 to 70 The UCC3895PW G4 is a phase-shift PWM controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UCC3895PW G4  
- **Type:** Phase-Shift PWM Controller  
- **Package:** TSSOP-20  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VDD):** 10V to 15V (max 20V)  
- **Output Current (Source/Sink):** 100mA (peak)  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Control Method:** Voltage-Mode or Current-Mode  

### **Descriptions:**
The UCC3895PW G4 is a high-performance phase-shift PWM controller designed for full-bridge or half-bridge power converters. It provides precise control over the switching transitions to minimize switching losses and improve efficiency in high-power applications. The device supports both voltage-mode and current-mode control schemes.

### **Features:**
- **Programmable Output Turn-On Delay** for adaptive dead-time control.  
- **Adjustable Frequency Oscillator** with synchronization capability.  
- **Soft-Start and Soft-Stop** functionality for controlled startup/shutdown.  
- **Error Amplifier** with bandwidth up to 10MHz.  
- **Under-Voltage Lockout (UVLO)** protection.  
- **Over-Current Protection (OCP)** with programmable threshold.  
- **4 Complementary Outputs** (2 high-side, 2 low-side) with adjustable dead time.  
- **Synchronization Input** for multi-phase operation.  
- **Low Power Consumption** in shutdown mode.  

This device is commonly used in telecom power supplies, server power systems, and industrial power converters.
