Description and Introduction

CMOS Dual 8-Bit Buffered Multiplying DACs The MAX7528JN 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:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 3V to 5.5V (set via external resistors)  
- **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:** 8-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The MAX7528JN is a high-efficiency, step-up (boost) DC-DC converter designed for low-power applications.  
- It integrates a power MOSFET switch, reducing external component count.  
- Features a fixed-frequency PWM control scheme for stable operation.  
- Suitable for battery-powered devices, portable electronics, and other applications requiring regulated higher voltages from lower input sources.  

### **Features:**  
- **Low Quiescent Current:** 100µA (typical)  
- **Internal Power MOSFET Switch:** Simplifies design and reduces external parts.  
- **Soft-Start Function:** Limits inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Short-Circuit Protection:** Enhances reliability in fault conditions.  
- **Adjustable Output Voltage:** Configured using external resistors.  

This information is based solely on the manufacturer's datasheet for the MAX7528JN.
