Introduction

AI Translation

The MAX1623 current-mode, PWM, DC-DC regulator is designed for 5V-input step-down applications. It features a 55mΩ(typ) PMOS switch and a 60mΩ(typ) NMOS synchronous-rectifier switch. Simple constant-offtime control allows switching frequencies up to 350kHz. Adjust the off-time with an external resistor RTOFF to optimize performance trade-offs among efficiency, component size, output switching noise, and cost. Idle Mode operation enhances light-load efficien

Features

AI Translation
  • The MAX1623 switch-mode buck regulator with synchronous rectification provides local CPU and bus-termination power in notebook and desktop computers.
  • An internal 55mΩ (typ), 3A PMOS power switch and 60mΩ (typ), 3A NMOS synchronous-rectifier switch deliver continuous load currents up to 3A from a 5V supply with 95% typical efficiency.
  • Output accuracy is ± 1 %, including line and load regulation.
  • The MAX1623 features constant-off-time, current-mode pulse-width-modulation (PWM) control with switching frequencies as high as 350kHz.
  • An external resistor at the TOFF pin sets the off-time, allowing optimum design flexibility in terms of switching frequency, output switching noise, and inductor size.
