The Austin LynxTM II SMT power modules are non-
isolated dc-dc converters that can deliver up to 10A of
output current with full load efficiency of 95% at 3.3V
output. These modules provide a precisely regulated
output voltage ranging from 0.75Vdc to 3.3Vdc,
programmable via an external resistor over a wide input
voltage range of 2.4Vdc to 5.5Vdc. The Austin LynxTM
II has a sequencing feature that enables designers to
implement various types of output voltage sequencing
when powering multiple voltages on a board. The
open-frame construction and small footprint enables
designers to develop cost- and space-efficient
solutions. In addition to sequencing, features include
remote On/Off, output voltage adjustment, remote
sense, over temperature and over current protection.
