Description and Introduction

Dual-Output Step-Down DC-DC Converter for PDA/Palmtop Computers The MAX1775EEE-T is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its factual specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 28V  
- **Output Voltage Range:** Adjustable from 2.7V to 28V  
- **Output Current:** Up to 2A (switch current limit)  
- **Switching Frequency:** 300kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP (Exposed Pad)  

### **Descriptions:**  
- The MAX1775EEE-T is a synchronous step-up DC-DC converter optimized for high-efficiency power conversion.  
- It integrates a low-resistance N-channel MOSFET switch and a synchronous rectifier for improved efficiency.  
- Suitable for battery-powered applications, portable devices, and industrial systems requiring regulated high-voltage outputs.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 1.8V to 28V.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Low Shutdown Current:** <1µA in shutdown mode.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Includes cycle-by-cycle current limiting.  
- **Thermal Shutdown:** Protects against overheating.

Description and Introduction

Dual-Output Step-Down DC-DC Converter for PDA/Palmtop Computers The MAX1775EEE-T is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP (Exposed Pad)  

### **Descriptions:**
The MAX1775EEE-T is a high-efficiency, step-up DC-DC converter optimized for low-input voltage applications, such as single-cell or dual-cell battery-powered devices. It integrates a synchronous rectifier for improved efficiency and requires minimal external components.  

### **Features:**
- **Low Start-up Voltage:** Operates down to 0.7V input.  
- **Synchronous Rectification:** Enhances efficiency.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 25µA (typical) in shutdown mode.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Overcurrent Protection:** Safeguards the device and load.  
- **Compact Package:** 16-QSOP with exposed pad for thermal dissipation.
