Description and Introduction

3.3V/5V/Adjustable-Output, Step-Up DC-DC Converters The MAX756ESA 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:** DC-DC Switching Regulators  
- **Output Type:** Adjustable  
- **Topology:** Step-Up (Boost)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.7V to 5.5V  
- **Output Current:** Up to 200mA (for 3.3V output)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 87%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-SOIC (MAX756ESA)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX756ESA is a CMOS, step-up DC-DC converter designed for low-input-voltage applications. It efficiently boosts input voltages as low as 0.7V to a regulated output voltage, making it suitable for battery-powered devices. The device includes an internal power MOSFET, minimizing external component count.  

### **Features:**  
- Low start-up voltage (0.7V)  
- Adjustable or preset output voltage (3.3V or 5V)  
- Low quiescent current (60µA typical)  
- Internal power MOSFET switch  
- No external Schottky diode required  
- Soft-start feature for reduced inrush current  
- Thermal shutdown protection  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LTC3525ESC6-3.3 --: Pin-compatible boost converter in a similar package with comparable input voltage range and output current, suitable drop-in for many MAX756 applications.
  • TPS61070DDCR --: High-efficiency synchronous boost converter with wide input range and low quiescent current, functionally equivalent for 3.3V/5V step-up designs.
  • NCP1402SN33T1G --: Low-power boost converter with fixed 3.3V output and small SOT-23 package, a cost-effective alternative for light-load step-up regulation.
  • LT1073CS8 --: Pin-compatible step-up DC-DC converter in SO-8 with similar boost topology and input range, widely used as a MAX756 substitute.
  • MC34063ACD --: Versatile DC-DC switching regulator that can be configured as a boost converter, low cost and readily available alternative.
  • LM2577S-ADJ --: Adjustable step-up switching regulator in a similar package, suitable for boost applications requiring higher current.
