MAX1710 Evaluation Kit
General Description
The MAX1710 evaluation kit (EV kit) demonstrates the
data sheet鈥檚 standard 7A notebook CPU application cir-
cuit (see MAX1710/MAX1711 data sheet). This DC-DC
converter steps down high-voltage batteries and/or AC
adapters, generating a precision, low-voltage CPU core
V
CC
rail.
The circuit was designed for a 7V to 24V battery range,
but accommodates from 4.5V to 24V. Some parameters,
such as load-transient response and maximum thermal
load capability, may be degraded by going outside the
7V to 24V range. The continuous output current rating,
based on worst-case MOSFET R
DS(ON)
, heat sinking,
and other thermal stress issues, is 5.5A at T
A
= +70擄C.
This EV kit is a fully assembled and tested circuit
board. It also allows the evaluation of the MAX1711.
