Features

AI Translation
  • The MAX8543/MAX8544 current-mode, constant-frequency PWM buck controllers operate from a 3V to 13.2V input supply and generate adjustable 0.8V to 0.9xV output voltages at loads up to 25A.
  • They feature adjustable switching frequency and synchronization for noise-sensitive applications.
  • The MAX8543/MAX8544 can start with (or without) a preexisting bias on the output, without discharging the output.
  • This feature simplifies tracking supply designs for core and I/O applications and redundant supply designs.
  • The MAX8543/MAX8544 use the DC resistance of the output inductor as the current-sense element for lossless, low-cost current sensing.
  • The current-sense threshold can be set to four discrete levels to accommodate inductors with different DC resistance values.
  • The MAX8544 features a power-OK monitor and two MAX8544 controllers that can operate at 180° out-ofphase for dual-output applications.
  • Prebias Startup/Monotonic
  • 1% Output Accuracy
  • Ceramic, Polymer, or Electrolytic Capacitors
  • 200kHz to 1MHz Adjustable Frequency
  • 160kHz to 1.2MHz Synchronization
  • Lossless, Foldback Current Limit
  • Overvoltage Protection
  • Enable (On/Off)
  • Adjustable Soft-Start
  • MAX8544 Latch-Off/Autorecovery Power-OK Monitor Out-of-Phase Clock Output
