Description and Introduction

Pulse-Width-Modulation (PWM) Control Circuit 16-SOIC 0 to 70 The TL594CDRG4 is a pulse-width modulation (PWM) control circuit manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** PWM Controller  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Output Type:** Dual Source/Sink  
- **Frequency Range:** Up to 300 kHz  
- **Duty Cycle Max:** 45%  
- **Supply Voltage (VCC):** 7V to 40V  
- **Output Current:** ±200 mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The TL594CDRG4 integrates all the functions required for PWM control in a single chip. It includes an on-chip adjustable oscillator, dead-time control, error amplifiers, and output control circuits. It is commonly used in power supply applications, DC-DC converters, and motor control systems.  

### **Features:**  
- Complete PWM control circuitry  
- Adjustable dead-time control  
- Internal error amplifiers  
- On-chip oscillator with sync capability  
- Dual alternating outputs  
- Under-voltage lockout  
- High current totem-pole outputs  

For more details, refer to the official TI datasheet.

Application Scenarios & Design Considerations

Pulse-Width-Modulation (PWM) Control Circuit 16-SOIC 0 to 70

Alternative Part Number

  • SG3525AN --: Industry-standard PWM controller with similar voltage-mode architecture and totem-pole outputs, widely used as a direct functional substitute in switching power supply designs.
  • UC3843AN --: Current-mode PWM controller offering comparable regulation performance and DIP-8 package, suitable for many applications where the TL594 is used.
  • MC34063AP --: Versatile DC-DC switching regulator controller that can replace the TL594 in simple buck/boost/inverting converter designs with minimal external component changes.
