Description and Introduction

Dual (Step-up and Step-down) PWM DC/DC Converter The LM2716MT is a dual monolithic switching regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 3V to 20V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 600 kHz (Buck Regulator), 350 kHz (Boost Regulator)  
- **Output Current:**  
  - Buck Regulator: Up to 1.5A  
  - Boost Regulator: Up to 2.5A  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
The LM2716MT integrates a step-down (buck) regulator and a step-up (boost) regulator in a single IC. It is designed for applications requiring efficient power conversion, such as battery-powered devices, portable electronics, and industrial systems.  

### **Features:**  
- **Dual Switching Regulators:** Combines a buck and boost regulator.  
- **Adjustable Output Voltages:** Set via external resistors.  
- **Synchronous Rectification:** Improves efficiency.  
- **Soft-Start Function:** Reduces inrush current.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation at low input voltages.  

The LM2716MT is optimized for compact designs with high efficiency and reliable performance.

Description and Introduction

Dual (Step-up and Step-down) PWM DC/DC Converter The LM2716MT is a dual DC/DC converter manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 3V to 20V  
- **Output Voltage Range:**  
  - Buck Converter: Adjustable down to 1.25V  
  - Boost Converter: Adjustable up to 24V  
- **Switching Frequency:** 600 kHz (Buck), 550 kHz (Boost)  
- **Output Current:**  
  - Buck Converter: Up to 1.5A  
  - Boost Converter: Up to 400mA  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin TSSOP (MT)  

### **Descriptions:**  
The LM2716MT integrates a step-down (buck) and a step-up (boost) converter in a single IC. It is designed for power management applications requiring both step-down and step-up regulation. The device operates at high switching frequencies, allowing the use of small external components.  

### **Features:**  
- **Dual Converter:** Combines a buck and boost regulator in one IC.  
- **Adjustable Outputs:** Both converters feature adjustable output voltages.  
- **Synchronization Capability:** External clock synchronization for noise-sensitive applications.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Low Shutdown Current:** <1µA in shutdown mode.  

This information is based solely on the manufacturer's datasheet.
