Description and Introduction

Step-Down Controllers with Synchronous Rectifier for CPU Power The MAX799CSE is a power management IC manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features based on available data:  

### **Manufacturer:** Maxim Integrated (Analog Devices)  
### **Part Number:** MAX799CSE  

### **Description:**  
The MAX799CSE is a highly integrated power management IC designed for notebook computers and portable devices. It combines multiple power supply functions, including a step-down (buck) controller, linear regulators, and power sequencing control.  

### **Key Features:**  
1. **Step-Down (Buck) Controller:**  
   - Input voltage range: **4.5V to 28V**  
   - Adjustable output voltage  
   - High efficiency synchronous rectification  

2. **Linear Regulators:**  
   - Includes multiple low-dropout (LDO) regulators  
   - Fixed or adjustable output options  

3. **Power Sequencing Control:**  
   - Ensures proper power-up and power-down sequencing  

4. **Protection Features:**  
   - Overvoltage protection (OVP)  
   - Undervoltage lockout (UVLO)  
   - Thermal shutdown  

5. **Package:**  
   - **16-pin SOIC (CSE package)**  

6. **Applications:**  
   - Notebook computers  
   - Portable devices  
   - Embedded systems  

### **Additional Notes:**  
- The MAX799CSE is optimized for battery-powered applications requiring multiple regulated voltages.  
- It operates over an extended temperature range, typically **-40°C to +85°C**.  

For exact electrical characteristics and application circuits, refer to the official datasheet from Maxim Integrated (Analog Devices).

Application Scenarios & Design Considerations

Step-Down Controllers with Synchronous Rectifier for CPU Power

Alternative Part Number

  • LTC1149CS --: High-efficiency step-down switching regulator controller with similar function and pinout, widely used as a MAX799 alternative.
  • MC34063ACD --: Versatile DC-DC switching regulator controller covering step-down/step-up/inverting topologies, a common lower-cost substitute.
  • LM2575T-ADJ --: Adjustable step-down switching regulator with integrated switch, suitable replacement when a complete regulator IC is acceptable.
  • LM2575S-ADJ --: Adjustable step-down switching regulator in a similar package, suitable for designs needing a simple integrated buck converter alternative.
