Description and Introduction

Quad-Output TFT LCD DC-DC Converters with Buffer The MAX1880EUG is a DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage Range:** Adjustable from 1.25V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin TSSOP (MAX1880EUG)  

### **Descriptions:**  
The MAX1880EUG is a high-efficiency, step-down DC-DC converter designed for low-power applications. It integrates a synchronous rectifier for improved efficiency and operates at a fixed 1MHz switching frequency, reducing external component size.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and reduces power loss.  
- **Low Dropout Operation:** Allows the output to stay in regulation even when the input voltage approaches the output voltage.  
- **Pulse-Width Modulation (PWM) Mode:** Ensures stable operation under varying load conditions.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overcurrent and Thermal Protection:** Safeguards the device under fault conditions.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Low Quiescent Current:** Enhances battery life in portable applications.

Application Scenarios & Design Considerations

Quad-Output TFT LCD DC-DC Converters with Buffer

Alternative Part Number

  • LT1945EMS --: Dual-channel step-up/down switching regulator in a small MSOP package, functionally similar to the MAX1880 for multi-output LCD bias supplies.
  • TPS65130RGER --: Dual-output boost and inverting converter for LCD bias applications, comparable function and package size to the MAX1880.
  • ISL98611IIZ --: Integrated LCD bias power supply with positive and negative outputs, suitable as a functional replacement for the MAX1880 in display bias circuits.
  • TPS61020DRCR --: Boost converter in the same class with integrated switch, suitable as a functional substitute for the MAX1880 boost regulator in portable power designs.
  • LT1935ES5 --: High-efficiency step-up DC-DC converter with comparable input voltage range and current capability, a common cross-reference for MAX1880 boost applications.
  • AP3012KTR-G1 --: Low-cost boost converter with similar switching topology and package options, usable as a second-source alternative when full MAX1880 features are not required.
