Description and Introduction

Step-up PWM DC/DC Converter Integrated with 4 Buffers The LM2711MT-ADJ is a switching regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4V to 20V  
- **Output Voltage Range:** Adjustable (1.25V to 18V)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 550kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-16  

### **Descriptions:**
The LM2711MT-ADJ is a dual monolithic switching regulator consisting of a step-down (buck) regulator and a step-up (boost) regulator. It is designed for high-efficiency power conversion applications and provides adjustable output voltages. The device integrates power switches, control circuitry, and protection features, making it suitable for battery-powered and portable systems.

### **Features:**
- **Dual Regulator:** Includes one buck and one boost converter.  
- **Adjustable Outputs:** Both regulators feature adjustable output voltages.  
- **High Efficiency:** Up to 90% efficiency for optimized power usage.  
- **Internal Power Switches:** Reduces external component count.  
- **Synchronizable:** External clock synchronization capability.  
- **Protection Features:** Includes thermal shutdown and current limiting.  
- **Low Shutdown Current:** <1µA in shutdown mode.
