Description and Introduction

3.3V/5V or Adjustable Output, Step-Up DC-DC Converters The MAX856CSA+T is a step-up DC-DC converter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Power Management IC  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 200mA  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
The MAX856CSA+T is a low-power, step-up DC-DC converter designed for battery-powered applications. It features a high-efficiency boost topology, allowing it to generate higher output voltages from very low input voltages (as low as 0.7V). The device is optimized for portable electronics, such as wireless sensors, medical devices, and handheld instruments.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 16µA (typical) for improved battery life.  
- **Internal Power Switch:** Simplifies design by eliminating the need for an external MOSFET.  
- **Pulse-Width Modulation (PWM) Control:** Ensures stable output under varying loads.  
- **Small Footprint:** 8-pin SOIC package for space-constrained applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

This information is based solely on manufacturer datasheets and technical documentation.

Application Scenarios & Design Considerations

3.3V/5V or Adjustable Output, Step-Up DC-DC Converters

Alternative Part Number

  • LTC3525ESC6-3.3#TRMPBF --: 3.3V step-up DC-DC converter in a small SC-70 package with similar boost topology and low quiescent current, suitable replacement for MAX856 applications.
  • TPS61023DRLR --: Boost converter with integrated switch and wide input range, functionally similar to MAX856 and available in a compact SOT-563 package.
  • AP3012KTR-G1 --: Low-cost step-up DC-DC converter with comparable switching frequency and output capability, offering a different series as a drop-in style alternative.
