Description and Introduction

Cascaded PWM Controller The LM5041SD is a high-voltage PWM controller manufactured by Texas Instruments (NS refers to National Semiconductor, which was acquired by TI).  

**Key Specifications:**  
- **Input Voltage Range:** 15V to 100V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Up to 1MHz (programmable)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-pin WSON (SD package)  

**Descriptions & Features:**  
- Designed for high-voltage DC-DC converters in telecom, industrial, and automotive applications.  
- Supports half-bridge and full-bridge topologies.  
- Integrated high-side and low-side gate drivers.  
- Programmable dead-time control for shoot-through prevention.  
- Soft-start functionality to reduce inrush current.  
- Under-voltage lockout (UVLO) protection.  
- Current-mode control for improved transient response.

Description and Introduction

Cascaded PWM Controller The LM5041SD is a high-voltage PWM controller manufactured by National Semiconductor (NSC).  

**Specifications:**  
- **Input Voltage Range:** 15V to 100V  
- **Operating Frequency:** Adjustable up to 1MHz  
- **Output Drive Current:** 1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Package:** 10-pin LLP (Leadless Leadframe Package)  
- **Operating Temperature Range:** -40°C to +125°C  

**Descriptions:**  
The LM5041SD is designed for high-voltage applications, including isolated and non-isolated power supplies. It integrates a high-voltage start-up regulator, reducing external component count.  

**Features:**  
- High-voltage start-up regulator (up to 100V)  
- Programmable oscillator frequency  
- Adjustable soft-start  
- Under-voltage lockout (UVLO)  
- Cycle-by-cycle current limiting  
- Error amplifier with reference voltage  
- Synchronization capability  

The device is optimized for efficiency and reliability in power supply designs.
