Description and Introduction

Six-Channel, High-Efficiency, Digital Camera Power Supplies The MAX1567 is a high-efficiency, step-up DC-DC converter designed for applications requiring a regulated output voltage from a single-cell lithium-ion (Li+) battery or other low-voltage sources. Below are the factual details about the MAX1567:  

### **Manufacturer:**  
- **MAX** (now part of **Analog Devices**)  

### **Key Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable from 2.5V to 5.5V (fixed 3.3V and 5V options available)  
- **Maximum Output Current:** Up to 1A (depending on input/output conditions)  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 10-pin µMAX® (3mm x 3mm)  

### **Descriptions:**  
- The MAX1567 integrates a synchronous rectifier for improved efficiency.  
- It features a low 0.7V startup voltage, making it suitable for single-cell battery applications.  
- The device includes internal soft-start and overcurrent protection.  

### **Features:**  
- **Synchronous Rectification** for high efficiency.  
- **Low Quiescent Current** (30µA typical).  
- **Adjustable or Fixed Output Voltage** options.  
- **Pulse-Width Modulation (PWM) Operation** for stable performance.  
- **Thermal Shutdown Protection** to prevent overheating.  
- **Small Footprint** due to the µMAX package.  

These specifications and features make the MAX1567 suitable for portable devices, USB-powered applications, and other low-voltage power conversion needs.
