Description and Introduction

Digitally Adjustable LCD Bias Supplies The MAX1620EEE+ is a step-down DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 29V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP (Quad Flat Small Outline Package)  

### **Descriptions:**
The MAX1620EEE+ is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated lower voltage from a higher input supply. It integrates a power switch, oscillator, and control logic, reducing external component count. The device operates in pulse-width modulation (PWM) mode for stable output under varying load conditions.

### **Features:**
- **Wide Input Voltage Range:** Supports 4V to 30V input.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **High Efficiency:** Up to 90%, reducing power dissipation.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  
- **Internal Power MOSFET:** Simplifies design and reduces external parts.  
- **Short-Circuit Protection:** Enhances reliability.  
- **Low Quiescent Current:** Typically 1.5mA for improved efficiency at light loads.  
- **Thermal Shutdown:** Protects the IC from overheating.  

This device is suitable for battery-powered systems, industrial controls, and portable electronics requiring efficient voltage conversion.
