MAX5038 - Dual-Phase / Parallelable / Average Current-Mode Controllers

General Description

The MAX5038/MAX5041 dual-phase, PWM controllers provide high-output-current capability in a compact package with a minimum number of external components.

Key Features

  • +4.75V to +5.5V or +8V to +28V Input Voltage Range.
  • Up to 60A Output Current.
  • Internal Voltage Regulator for a +12V or +24V Power Bus.
  • True Differential Remote Output Sensing.
  • Two Out-Of-Phase Controllers Reduce Input Capacitance Requirement and Distribute Power Dissipation.
  • Average Current-Mode Control Superior Current Sharing Between Individual Phases and Paralleled Modules Accurate Current Limit Eliminates MOSFET and Inductor Derating.

19-2514; Rev 3; 8/04 MAX5038/MAX5041 Dual-Phase, Parallelable, Average Current-Mode Controllers General Description The MAX5038/MAX5041 dual-phase, PWM controllers provide high-output-current capability in a compact package with a minimum number of external components. The MAX5038/MAX5041 utilize a dual-phase, average current-mode control that enables optimal use of low RDS(ON) MOSFETs, eliminating the need for external heatsinks even when delivering high output currents. Differential sensing enables accurate control of the output voltage, while adaptive voltage positioning provides optimum transient response. An internal regulator enables operation with input voltage ranges of +4.75V to +5.5V or +8V to +28V.
