Description and Introduction

+5V fixed output, 10W CMOS step-up switching regulator. 10% output accuracy The MAX641BCSA is a voltage regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX641BCSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Input Voltage Range:** 4V to 11.5V  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 100mA  
- **Dropout Voltage:** 300mV (typical at 100mA load)  
- **Quiescent Current:** 40µA (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Line Regulation:** 0.05%/V (typical)  
- **Load Regulation:** 0.5% (typical)  

### **Descriptions:**
The MAX641BCSA is a low-dropout (LDO) linear voltage regulator designed for applications requiring a stable 5V supply with minimal power loss. It is optimized for battery-powered systems due to its low quiescent current and low dropout voltage.  

### **Features:**
- **Low Dropout Voltage:** 300mV at 100mA load  
- **Low Quiescent Current:** 40µA (typical)  
- **Fixed 5V Output**  
- **Thermal Shutdown Protection**  
- **Short-Circuit Protection**  
- **Stable with Low-ESR Capacitors**  
- **Small Footprint (8-pin SOIC)**  

This information is based solely on the manufacturer’s datasheet and does not include any additional recommendations or guidance.

Alternative Part Number

  • LTC1148CS8 --: Step-up switching regulator controller in an 8-pin SOIC package with comparable boost converter function and pin-compatible topology.
  • MC34063ACD --: Widely available general-purpose DC-DC switching regulator controller usable as a boost converter replacement with similar input voltage range.
  • TL497ACD --: Classic switching voltage regulator IC in SOIC package offering boost capability and a similar control architecture for legacy designs.
  • LTC1144CS8 --: Pin-compatible switched-capacitor voltage converter in an 8-pin SOIC package with similar inverting/step-up capability, widely available and a common drop-in substitute for MAX641 designs.
  • ICL7660CSA --: Classic industry-standard switched-capacitor voltage converter in SOIC-8, functionally similar to the MAX641 for charge-pump applications and easy to source as a second source.
  • TC7660COA --: SOIC-8 charge-pump voltage converter with comparable operating range and pinout, offering a cost-effective alternative when the MAX641 is unavailable.
