Description and Introduction

Compact / High-Efficiency / Dual-Output Step-Up and LCD Bias DC-DC Converter The MAX1677EEE is a step-up DC-DC converter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 16-QSOP (EE)  
- **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 94%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX1677EEE is a high-efficiency, low-power, step-up DC-DC converter designed for battery-powered applications. It is optimized for low input voltages, making it suitable for single-cell or dual-cell battery systems. The device features an internal 0.3Ω N-channel MOSFET switch and includes a built-in low-battery detector.  

### **Features:**  
- **Wide Input Voltage Range:** Operates from 0.7V to 5.5V  
- **Adjustable Output Voltage:** Configurable from 2V to 5.5V  
- **High Efficiency:** Up to 94%  
- **Low Quiescent Current:** 16µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Internal Power MOSFET Switch:** Reduces external component count  
- **Low-Battery Detector:** Provides system monitoring capability  
- **500kHz Switching Frequency:** Allows for small external components  
- **Thermal Shutdown Protection:** Prevents overheating  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Compact / High-Efficiency / Dual-Output Step-Up and LCD Bias DC-DC Converter

Alternative Part Number

  • LT1945EMS --: Dual-output step-up/step-down DC-DC converter in MSOP-16 with similar dual boost/inverting topology and input range, a common cross for MAX1677 designs.
  • TPS65130RGER --: Dual-output boost plus inverting converter in a small QFN package, functionally comparable to the MAX1677 for LCD bias and dual-rail supplies.
  • ISL97516IUZ --: Compact dual-output boost/inverting DC-DC converter offering similar functionality and pin-count, suitable as a second-source alternative.
  • TPS61020DRCR --: Boost converter with similar input/output voltage range and current capability, pin-compatible footprint in a small package, widely available and lower cost.
  • LT1308B --: High-efficiency step-up DC-DC converter with comparable switching frequency and output current, suitable drop-in for many MAX1677 boost applications.
  • NCP1402SN50T1G --: Compact boost regulator offering similar functionality for low-power step-up designs, good second-source option when exact MAX1677 features are not critical.
  • TPS61030PWPR --: Boost converter with similar input voltage range and current capability, widely available and pin-compatible in function for many MAX1677 applications.
  • LT1308BCS8 --: High-efficiency boost DC-DC converter with comparable switching frequency and output current, suitable drop-in functional replacement.
  • MC34063ADR2G --: Versatile general-purpose DC-DC converter IC that can be configured as a boost regulator, low cost and broadly stocked alternative.
