Description and Introduction

Small / High-Efficiency / Five-Channel Digital Still Camera Power Supply The MAX1565ETJ is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V  
- **Output Current:** Up to 600mA (at 3.3V output from a 1.8V input)  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TQFN (5mm x 5mm)  

### **Descriptions:**  
- The MAX1565ETJ is designed for applications requiring high efficiency from low input voltages, such as single-cell or dual-cell battery-powered devices.  
- It integrates synchronous rectification to minimize power loss and improve efficiency.  
- The device includes a true shutdown mode, reducing supply current to less than 1µA when disabled.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Synchronous Rectification:** Enhances efficiency.  
- **True Shutdown Mode:** Disconnects the load from the input.  
- **Internal Soft-Start:** Prevents inrush current.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Small Footprint:** 32-pin TQFN package for space-constrained designs.
