Partnumber Manufacturer Quantity Availability
LTC3423EMS LINEAR 150 In Stock

Description and Introduction

Low Output Voltage, 3MHz Micropower Synchronous Boost Converters The LTC3423EMS is a high efficiency, synchronous step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 0.5V to 5V  
- **Output Voltage Range:** Up to 5.25V  
- **Output Current:** Up to 400mA  
- **Switching Frequency:** 1MHz  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 20µA (typical)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** MSOP-10  

### **Descriptions:**  
The LTC3423EMS is designed for low input voltage applications, making it suitable for single-cell or dual-cell alkaline/NiMH battery-powered devices. It features automatic Burst Mode® operation for improved efficiency at light loads and includes internal synchronous rectification to minimize external components.  

### **Features:**  
- **True Disconnect** in shutdown mode  
- **Soft-Start** for controlled inrush current  
- **Synchronous Rectification** for high efficiency  
- **Burst Mode Operation** for low quiescent current  
- **Internal Compensation** for simplified design  
- **Short-Circuit Protection**  

The device is commonly used in portable electronics, energy harvesting, and low-power wireless applications.

Description and Introduction

Low Output Voltage, 3MHz Micropower Synchronous Boost Converters The LTC3423EMS is a high efficiency, synchronous step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 0.5V to 5V  
- **Output Voltage Range:** Up to 5.25V (adjustable)  
- **Switching Frequency:** 1MHz (typical)  
- **Maximum Output Current:** 500mA (at 3.3V output from a 1V input)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 20µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead MSOP  

### **Descriptions:**  
The LTC3423EMS is designed for applications requiring a regulated output voltage from very low input voltages, such as single-cell or two-cell battery-powered systems. It integrates synchronous rectification to improve efficiency and reduce external component count.  

### **Features:**  
- **True Low-Voltage Operation:** Starts up with inputs as low as 0.5V.  
- **Synchronous Rectification:** Eliminates the need for an external Schottky diode.  
- **Automatic Burst Mode® Operation:** Enhances efficiency at light loads.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Shutdown Current:** <1µA when disabled.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.
