Description and Introduction

CURRENT MODE PWM CONTROLLER Part Number: **SG2842D**  

**Manufacturer:** ON Semiconductor  

**Specifications:**  
- **Category:** Integrated Circuits (ICs)  
- **Family:** Power Management (PMIC)  
- **Type:** PWM Controller  
- **Topology:** Flyback, Forward  
- **Output Type:** Transistor Driver  
- **Number of Outputs:** 1  
- **Frequency - Switching:** Up to 500kHz  
- **Duty Cycle (Max):** 50%  
- **Supply Voltage (Vcc/Vdd):** 8.5V to 30V  
- **Operating Temperature:** -40°C to +85°C  
- **Package/Case:** SOIC-8  

**Descriptions:**  
The SG2842D is a pulse-width modulation (PWM) controller IC designed for power supply applications. It provides precise control for switching regulators, supporting flyback and forward converter topologies. It includes features such as under-voltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start capability.  

**Features:**  
- Adjustable switching frequency up to 500kHz  
- Under-voltage lockout (UVLO) protection  
- Current limiting for overload protection  
- Soft-start function for controlled startup  
- Low standby power consumption  
- Compatible with voltage-mode and current-mode control  
- High noise immunity  

For detailed electrical characteristics, refer to the manufacturer’s datasheet.
