MAX1843 - 2.7A / 1MHz / Low-Voltage / Step-Down Regulator

MAX1843 Description

19-1986; Rev 1; 3/02 KIT EVALUATION E BL LA AVAI 2.7A, 1MHz, Low-Voltage, Step-Down Regulator with Internal Synchronous Rectification in QFN Package.
The MAX1843 constant-off-time, pulse-width modulated (PWM) step-down DC-DC converter is ideal for use in 5V and 3.

MAX1843 Features

* an internal PMOS power switch and internal synchronous rectification for high efficiency and reduced component count. An external Schottky diode is not required. The internal 90mΩ power switch and 70mΩ NMOS synchronous-rectifier switch easily deliver continuous load currents up to 2.7A. The MAX1843
