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 (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX856CSA-T  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Options:** Adjustable (2.5V to 5.5V) or Fixed (3.3V, 5V)  
- **Output Current:** Up to 150mA (depends on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **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 an internal 0.3Ω N-channel MOSFET switch and operates efficiently from very low input voltages (down to 0.7V). The device is optimized for small, portable electronics requiring regulated voltage from single-cell or dual-cell battery inputs.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Adjustable/Fixed Output:** Supports adjustable (via external resistors) or fixed output voltages.  
- **High Efficiency:** Up to 90% efficiency with minimal external components.  
- **Low Quiescent Current:** Typically 50µA (shutdown mode: <1µA).  
- **Internal MOSFET Switch:** Eliminates need for an external switch.  
- **Compact Design:** Small 8-pin SOIC package for space-constrained applications.  
- **Overcurrent Protection:** Built-in to safeguard the device.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
