Description and Introduction

Quad-Output TFT LCD DC-DC Converters with Buffer The MAX1880EUG+ is a step-up (boost) 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:** Adjustable from 2.5V to 5.5V (fixed or via external resistors)  
- **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  
- **Package:** 24-TSSOP (Thin Shrink Small Outline Package)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX1880EUG+ is a high-efficiency, low-noise, step-up DC-DC converter designed for battery-powered applications. It integrates a power MOSFET switch and supports low input voltages, making it suitable for single-cell or dual-cell battery systems.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Adjustable/Fixed Output Voltage**  
- **Internal Power MOSFET Switch**  
- **Low Quiescent Current:** 20µA (typical)  
- **Pulse-Frequency Modulation (PFM) for Improved Efficiency at Light Loads**  
- **Soft-Start Function**  
- **Thermal Shutdown Protection**  

This device is commonly used in portable electronics, medical devices, and energy-harvesting applications.

Application Scenarios & Design Considerations

Quad-Output TFT LCD DC-DC Converters with Buffer

Alternative Part Number

  • TPS61020DRCR --: Boost converter in the same class with comparable input/output voltage range and current capability; different series and pin-compatible footprint options make it a strong functional substitute.
  • LT1935ES5#TRPBF --: High-efficiency boost regulator with similar switching frequency and current rating, suitable as a drop-in functional replacement for the MAX1880 boost converter.
  • AP3012KTR-G1 --: Low-cost boost converter with comparable voltage and current specifications, offering a different naming series and good availability as an alternative.
  • LT1945EMS#PBF --: Dual-channel step-up/step-down DC-DC converter in a similar small package, offering comparable multi-output regulation for the same power-supply role.
  • TPS65130RGER --: Dual-output positive/negative boost converter with integrated switches, suitable as a functional substitute for multi-rail LCD/bias supply applications.
  • ISL97516IUZ --: Compact high-frequency boost converter with integrated FET, providing a similar switching-regulator function in a small package.
