Description and Introduction

Buck Pulse Width Modulator Stepdown Voltage Regulator Here are the factual details about part **UC2578DP** from Ic-phoenix technical data files:

### **Manufacturer**:  
- **Unitrode Corporation** (now part of **Texas Instruments** after acquisition).

### **Specifications**:  
- **Type**: Switching Regulator Controller (Buck, Boost, Flyback, or Forward Converter).  
- **Topology**: Supports multiple configurations (voltage or current mode).  
- **Input Voltage Range**: Typically **8V to 40V** (operational).  
- **Output Voltage**: Adjustable via external components.  
- **Switching Frequency**: Adjustable (typically up to **100kHz**).  
- **Output Current**: Dependent on external MOSFET/transistor (controller, not integrated).  
- **Duty Cycle**: Up to **90%** (varies with topology).  
- **Protections**: Includes undervoltage lockout (UVLO), current limiting, and thermal shutdown.  

### **Descriptions and Features**:  
- **Purpose**: Designed for DC-DC power supply applications.  
- **Package**: **DIP-16** (Dual Inline Package, 16 pins).  
- **Control Method**: Voltage-mode or current-mode PWM control (configurable).  
- **Efficiency**: High efficiency due to low standby current and optimized switching.  
- **Applications**: Used in industrial power systems, telecom equipment, and automotive electronics.  
- **Key Features**:  
  - Soft-start capability.  
  - Precision reference voltage (**5V ±1%**).  
  - Compatible with synchronous rectification.  

For exact datasheet parameters, refer to the official **Texas Instruments/Unitrode UC2578DP datasheet**.
