Description and Introduction

Current-Mode PWM Controllers with Integrated Startup Circuit for Isolated Power Supplies The MAX5014CSA is a high-speed, 14-bit digital-to-analog converter (DAC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 14-bit  
- **Interface:** Parallel  
- **Supply Voltage:** +5V  
- **Output Type:** Current  
- **Settling Time:** 35ns (typical)  
- **DNL (Differential Nonlinearity):** ±0.5 LSB (max)  
- **INL (Integral Nonlinearity):** ±1 LSB (max)  
- **Power Consumption:** 150mW (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 24-pin SOIC  

### **Descriptions:**  
The MAX5014CSA is a high-performance, 14-bit DAC designed for applications requiring fast signal generation and precision. It features a parallel interface for rapid data loading and provides a current output that can be converted to a voltage using an external amplifier.  

### **Features:**  
- **High-Speed Operation:** 35ns settling time  
- **Low Glitch Energy:** Ensures clean output transitions  
- **Single +5V Supply Operation:** Simplifies power requirements  
- **On-Chip Output Amplifier:** Supports voltage output configurations  
- **TTL/CMOS-Compatible Inputs:** Easy interfacing with digital logic  
- **Internal Reference:** Optional use of an external reference  

This DAC is suitable for applications such as waveform generation, automatic test equipment, and high-speed instrumentation.

Application Scenarios & Design Considerations

Current-Mode PWM Controllers with Integrated Startup Circuit for Isolated Power Supplies

Alternative Part Number

  • LM3478MM --: Widely available low-side N-channel controller in the same class as the MAX5014; different series name and pin-compatible function for boost/flyback designs.
  • UC3843BD1 --: Industry-standard current-mode PWM controller with similar drive and compensation features; a well-known drop-in style alternative from a different series.
  • NCP1252ADR2G --: Current-mode controller with comparable gate drive and protection features, offered in a different product family for easy distinction from the original.
  • NCP1034DR2G --: High-voltage current-mode controller suitable for boost and flyback topologies, offering comparable drive strength and protection features as a functional alternative.
  • UC3843A --: Industry-standard current-mode PWM controller in 8-pin SOIC, very common and cost-effective alternative for boost/flyback designs, though switching frequency and compensation may need retuning.
