Features and Benefits

  • Dual High-Voltage Step-Down Controllers to Minimize Board-Area Occupancy
  • Meets Stringent OEM Module Power Consumption and Performance Specifications
  • 17μA Quiescent Current in Skip Mode
  • ±1.5% Output-Voltage Accuracy: 5.0V/3.3V, Fixed or Adjustable by External Resistor-Divider
  • EMI Reduction Features and Adjustable Fixed-Frequency Operation to Reduce Signal Interference
  • Optimized Application Layout and Components for Quick Design Implementation
  • Jumpers and Test Points on Key Nodes for Simplified Evaluation
  • Proven PCB Layout
  • Fully Assembled and Tested

Product Details

The MAX20034 evaluation kit (EV kit) is a fully assembled and tested application circuit that simplifies the evaluation of the MAX20034 high-efficiency 400kHz/2.2MHz, 36V, dual buck controller IC.

This EV kit operates from 3.5V to 42V supply and provides two synchronous step-down outputs by switching at 400kHz/2.2MHz, with each one 180° out of phase from the other. The frequency and output voltages can be adjusted using external resistors. SYNC input programmability enables three frequency modes for optimized performance: forced fixed-frequency operation, skip mode with ultra-low quiescent current, and synchronized external clock frequency.

Applications

  • Distributed DC Power Systems
  • Navigation and Radio Head Units
  • POL Applications for Automotive Power
