Description and Introduction

OFDM Narrowband Power Line Networking System on Chip **Manufacturer:** STMicroelectronics  

**Part Number:** ST7590  

**Specifications:**  
- **Category:** Power Management IC  
- **Type:** AC/DC Controller  
- **Topology:** Quasi-Resonant (QR) Flyback  
- **Input Voltage Range:** 85 VAC to 265 VAC  
- **Output Power:** Up to 15 W (depending on design)  
- **Switching Frequency:** Adjustable (typically up to 130 kHz)  
- **Standby Power Consumption:** <30 mW  
- **Protection Features:**  
  - Overvoltage Protection (OVP)  
  - Overcurrent Protection (OCP)  
  - Overload Protection (OLP)  
  - Short-Circuit Protection (SCP)  
  - Thermal Shutdown  

**Descriptions:**  
The ST7590 is a high-performance, low-power AC/DC controller designed for offline power supplies. It operates in quasi-resonant mode for improved efficiency and reduced EMI. The device integrates multiple protection mechanisms, making it suitable for compact and reliable power supply designs.  

**Features:**  
- Primary-side regulation (PSR) for simplified design  
- Built-in high-voltage startup circuit  
- Valley switching for reduced switching losses  
- Frequency jittering for lower EMI  
- Adjustable soft-start  
- Green-mode operation for low standby power  

(Note: For detailed electrical characteristics, refer to the official ST7590 datasheet.)
