Description and Introduction

100V Push-Pull Current Mode PWM Controller The LM5030SD is a high-voltage pulse width modulation (PWM) controller manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 15V to 100V  
- **Operating Frequency:** Adjustable up to 1MHz  
- **Output Drive Current:** 1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **UVLO (Undervoltage Lockout):** 8.6V (turn-on), 7.4V (turn-off)  
- **Package:** 10-pin LLP (Leadless Leadframe Package)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The LM5030SD is designed for high-voltage DC-DC converter applications, including telecom, industrial, and automotive systems. It integrates a high-voltage startup regulator, PWM controller, and gate driver, reducing external component count.  

### **Features:**  
- **High-Voltage Startup Regulator:** Operates directly from input voltages up to 100V.  
- **Adjustable Oscillator Frequency:** Programmable via external resistor.  
- **Synchronous Rectifier Control:** Supports half-bridge and full-bridge topologies.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Thermal Shutdown:** Prevents overheating.  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to NSC's official documentation.

Description and Introduction

100V Push-Pull Current Mode PWM Controller The LM5030SD is a high-voltage PWM controller manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Input Voltage Range:** 15V to 100V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle:** Up to 50% (for push-pull topology)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-pin WSON (SD)  

### **Descriptions:**  
The LM5030SD is a high-performance PWM controller designed for high-voltage DC-DC converters. It supports half-bridge, full-bridge, and push-pull topologies. It includes features like soft-start, cycle-by-cycle current limiting, and adjustable dead-time control for improved efficiency and reliability.  

### **Features:**  
- Wide input voltage range (15V to 100V)  
- High-frequency operation (up to 1MHz)  
- Programmable soft-start  
- Under-voltage lockout (UVLO)  
- Adjustable dead-time control  
- Cycle-by-cycle current limiting  
- Thermal shutdown protection
