Description and Introduction

12V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controller The MAX1771ESA is a step-up DC-DC controller manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX1771ESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage Range:** Adjustable up to 28V  
- **Switching Frequency:** 300kHz (fixed)  
- **Maximum Output Current:** Dependent on external components  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1771ESA is a high-efficiency, step-up DC-DC controller designed for battery-powered applications. It drives an external N-channel MOSFET to regulate output voltage with minimal external components. The device is optimized for low-voltage inputs and provides stable power conversion with adjustable output voltage.  

### **Features:**  
- **Wide Input Voltage Range (2V to 16.5V)** – Suitable for battery-powered systems.  
- **Adjustable Output Voltage (Up to 28V)** – Configurable via external resistors.  
- **High Efficiency (Up to 94%)** – Optimized for power-sensitive applications.  
- **Low Quiescent Current (110µA)** – Enhances battery life.  
- **Fixed-Frequency PWM Operation (300kHz)** – Reduces output ripple and noise.  
- **External MOSFET Drive** – Allows flexibility in power handling.  
- **Undervoltage Lockout (UVLO)** – Protects against low input voltage conditions.  
- **Thermal Shutdown** – Prevents overheating damage.  

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

Application Scenarios & Design Considerations

12V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controller

Alternative Part Number

  • LTC1871EMS --: Boost/SEPIC/inverting DC-DC controller with similar wide input range and external MOSFET drive, direct functional replacement in most MAX1771 boost designs.
  • MC34063A --: Classic general-purpose DC-DC switching regulator controller covering boost and inverting topologies; widely available and low cost, though switching frequency and efficiency are lower.
  • TL494 --: Versatile PWM controller usable for boost and inverting converter designs; different architecture but a common, well-stocked alternative when MAX1771 is unavailable.
