New Maxim Product Highlights

Maxim Integrated presents new Product Highlights

36V, 220kHz to 2.2MHz, 4A/6A/8A Fully Integrated Automotive Step-Down Converters

The MAX20004/MAX20006/MAX20008 are small, synchronous, automotive buck converter devices with integrated high-side and low-side MOSFETs. The device family can deliver up to 8A with input voltages from 3.5V to 36V, while using only 25µA quiescent current at no load. Voltage quality can be monitored by observing the active-low RESET signal. The devices can operate in dropout by running at 98% duty cycle, making them ideal for automotive applications.


Key Features

  • Operating VIN Range of 3.5V to 36V
  • 25µA Quiescent Current in Skip Mode
  • 220kHz to 2.2MHz Adjustable Frequency
  • Fixed 5ms Internal Soft-Start
  • Programmable 1V to 10V Output, or 3.3V and 5.0V Fixed-Output Options Available
  • 98% Duty-Cycle Operation with Low Dropout

3.2MHz, 500mA Dual Step-Down Converters for Automotive Cameras

The MAX20019/MAX20020 are 2.2MHz and 3.2MHz dual step-down converters with integrated high-side and low-side MOSFETs. The high-voltage step-down converter is designed for continuous operation up to 17V input voltages. The output voltage is factory preset. Buck 1 is preset to 3.3V, 3.0V, or 2.8V. Buck 2 is preset to 1.8V, 1.5V, 1.2V, or 1V. Another option is Buck 1 preset to 5V and Buck 2 preset to 3.3V.


Key Features

  • 2mm x 3mm x 0.75mm 10-pin TDFN with an Exposed Pad
  • 2.2MHz and 3.2MHz Operation Allows Smaller System Size
  • No External Components Needed for Soft-Start
  • 500mV Enable Hysteresis Allows for Long, Low-Cost Cables During Slow Starts
  • Optional Spread-Spectrum Frequency Modulation
  • Pinout Placement Allows for Tight PCB Layout of Switching Nodes
  • Overvoltage Protection, Thermal Shutdown, Short-Circuit Protection
  • Wide 3.5V to 17V Input Voltage Range for Power-Over-Coax
  • Automotive Temperature Range -40°C to +125°C
  • AEC-Q100 Qualified


  • Automotive Point-of-Load
  • Surround-View Camera Power Supplies
