Description and Introduction

Dual LNB supply and control IC with step-up and I2C interface The LNBH24 is a highly integrated, low-noise block downconverter (LNB) power supply and control IC manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 8V to 28V  
- **Output Current for LNB:** Up to 500mA  
- **Standby Current Consumption:** <1µA (typical)  
- **Switching Frequency:** 500kHz (fixed)  
- **Output Voltage for LNB:** Adjustable (13V/18V)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** PowerSO-10  

### **Descriptions:**  
The LNBH24 is designed to provide power and control signals to satellite LNBs. It integrates a step-up DC-DC converter, voltage regulators, and control circuitry in a single chip. It supports DiSEqC (Digital Satellite Equipment Control) 2.x protocol for communication with satellite receivers.  

### **Features:**  
- **Integrated DC-DC Boost Converter:** Efficiently steps up input voltage to required LNB levels.  
- **Low Standby Current:** Minimizes power consumption when inactive.  
- **DiSEqC 2.x Compliant:** Supports tone and data burst communication.  
- **Short-Circuit Protection:** Safeguards against output faults.  
- **Thermal Shutdown:** Prevents overheating.  
- **Adjustable Output Voltage:** Selectable 13V/18V for horizontal/vertical polarization.  
- **High Efficiency:** Optimized for power savings.  

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