MAX1623

3A / Low-Voltage / Step-Down Regulator

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. This device is av

MAX1623 General Description

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 60m Ω (typ), 3A NMOS synchronous-rectifier switch deliver continuous load currents up to 3A from a 5V.
