- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin TSSOP  

### **Descriptions:**  
The MAX1747EUP+T is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated output voltage from a wide input range. It integrates a high-side N-channel MOSFET and features pulse-width modulation (PWM) control for stable performance.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 36V)**  
- **Adjustable Output Voltage (1.25V to 10V)**  
- **Internal N-Channel MOSFET Switch**  
- **500kHz Fixed-Frequency PWM Operation**  
- **Low Dropout Operation**  
- **Overcurrent and Thermal Protection**  
- **Soft-Start Functionality**  
- **TSSOP Package for Space-Constrained Applications**  

This device is commonly used in industrial, automotive, and telecom applications where efficient power conversion is required.

Application Scenarios & Design Considerations

Triple Charge-Pump TFT LCD DC-DC Converter

Alternative Part Number

  • TPS65130RGER --: Dual-output boost/inverting DC-DC converter in a similar small package, functionally comparable to the MAX1747 for LCD bias supply applications.
  • LT3580EMS8E#PBF --: Versatile boost/inverting converter with integrated switch, suitable as a functional replacement in similar power supply designs.
  • MC34063ADR2G --: Widely available general-purpose DC-DC switching regulator that can be configured for boost or inverting topologies, offering a low-cost fallback option.
  • LT3582EUD#PBF --: Dual-channel boost/inverting DC-DC converter in a small package, suitable as a functional replacement for dual-rail bias generation; distinct naming from the source.
  • ISL98611IIZ-T --: Integrated LCD bias power supply with positive and negative outputs, comparable application role to the MAX1747; different prefix and series for clear identification.
