General Description
The MAX1776 high-efficiency step-down converter pro-
vides an adjustable output voltage from 1.25V to V
IN
from
supply voltages as high as 24V. An internal current-limit-
ed 0.4
MOSFET delivers load currents up to 600mA.
Operation to 100% duty cycle minimizes dropout volt-
age (240mV at 600mA).
The MAX1776 has a low 15μA quiescent current to
improve light-load efficiency and conserve battery life.
The device draws only 3μA while in shutdown.
High switching frequencies (up to 200kHz) allow the
use of tiny surface-mount inductors and output capaci-
tors. The MAX1776 is available in an 8-pin μMAX pack-
age, which uses half the space of an 8-pin SO. For
increased output drive capability, use the MAX1626/
MAX1627 step-down controllers, which drive an exter-
nal P-channel MOSFET to deliver up to 20W.
