Description and Introduction

DC-DC CONVERTER CONTROL CIRCUITS The MC34063EBD is a monolithic control circuit that contains the primary functions required for DC-to-DC converters. It is designed for step-down, step-up, and voltage-inverting applications with minimal external components.  

### **Manufacturer:**  
- **ON Semiconductor**  

### **Specifications:**  
- **Input Voltage Range:** 3V to 40V  
- **Output Voltage Range:** Adjustable from 1.25V to 40V  
- **Output Switch Current:** Up to 1.5A (peak)  
- **Oscillator Frequency:** 100kHz (typical)  
- **Duty Cycle Adjustable:** Up to 100%  
- **Low Standby Current:** Typically 2.5mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
- The MC34063EBD is a versatile DC-DC converter IC that can be configured for buck, boost, and inverting topologies.  
- It includes an internal temperature-compensated reference, comparator, oscillator, PWM control, and high-current output switch.  
- Suitable for battery-powered applications, power supplies, and voltage regulation.  

### **Features:**  
- **Wide Input Voltage Range (3V to 40V)**  
- **Adjustable Output Voltage**  
- **High Efficiency Switching Regulator**  
- **Short-Circuit Current Limiting**  
- **Low Standby Current**  
- **Internal Reference Voltage (1.25V)**  
- **Thermal Shutdown Protection**

Application Scenarios & Design Considerations

DC-DC CONVERTER CONTROL CIRCUITS

Alternative Part Number

  • MC34063AP1G --: Widely available DC-DC converter IC with the same MC34063 core function, different suffix and package, suitable drop-in for many designs.
  • LTC34063 --: Equivalent 34063-series switching regulator from a different vendor and series prefix, offering similar voltage and current capability.
  • AP34063 --: Alternative 34063-family DC-DC converter with a distinct manufacturer prefix, pin-compatible in most applications.
  • MC33063ADR2G --: Pin-compatible DC-DC converter IC with the same function and similar electrical ratings, widely available and well documented.
  • LM2596S-ADJ --: Adjustable step-down regulator that can replace the MC34063 in many buck converter designs with higher current capability.
  • XL6009E1 --: Versatile switching regulator IC often used as a drop-in functional substitute for MC34063-based converters at low cost.
