Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low I The MAX776 is a power management IC (PMIC) manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** Typically supports a wide input range (e.g., 2.7V to 5.5V).  
- **Output Voltage:** Configurable or fixed, depending on the variant (e.g., buck/boost/LDO outputs).  
- **Regulator Types:** May include buck converters, boost converters, and LDOs.  
- **Efficiency:** High efficiency (up to 95% for switching regulators).  
- **Current Output:** Varies by regulator (e.g., up to several amps for buck converters).  
- **Operating Temperature Range:** Typically **-40°C to +85°C** or **-40°C to +125°C**.  
- **Package Options:** Available in small form-factor packages (e.g., TQFN, WLP).  

### **Descriptions:**  
- The **MAX776** is a **multi-output PMIC** designed for portable and battery-powered applications.  
- It integrates multiple power rails (buck, boost, LDOs) to reduce board space and improve efficiency.  
- Often used in **wearables, IoT devices, and smartphones** for power management.  

### **Features:**  
- **Multiple Power Rails:** Combines buck, boost, and LDO regulators in a single chip.  
- **Dynamic Voltage Scaling:** Supports adjustable output voltages for power optimization.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **I²C Interface:** Allows programmable control of output voltages and sequencing.  
- **Protection Features:** Includes overcurrent, overvoltage, and thermal shutdown protection.  

For exact specifications, refer to the **MAX776 datasheet** from Maxim Integrated (Analog Devices).

Application Scenarios & Design Considerations

-5V/-12V/-15V or Adjustable, High-Efficiency, Low I

Alternative Part Number

  • LTC3105 --: Analog Devices (now owns Maxim) offers the LTC3105 as a similar low-input-voltage boost converter for energy harvesting, functionally comparable to the MAX776.
  • TPS61200 --: The TPS61200 is a widely available low-input boost converter with similar ultra-low voltage startup capability, suitable as a functional replacement.
  • BQ25504 --: The BQ25504 is a nano-power energy-harvesting boost charger with very low input voltage operation, matching the MAX776's typical application space.
