PRODUCT OVERVIEW
The OKDx-T/40-W12 series are high effi-
ciency, digital point-of-Load (PoL) DC-DC
power converters capable of delivering
40A/132W. Available in three different pack-
age formats, through-hole, single-in-line,
and surface mount, these converters have a
typical efficiency of 97.2%. PMBus™ compat-
ibility allows monitoring and configuration of
critical system-level performance require-
ments. Apart from standard PoL performance
and safety features like OVP, OCP, OTP, and
UVLO, these digital converters have advanced
features: digital current sharing (full power,
no derating), non-linear transient response,
optimized dead time control, synchronization,
and phase spreading. These converters are
ideal for use in telecommunications, network-
ing, and distributed power applications.
Power Management via PMBus™
Configurable soft-start/stop
Configurable output voltage (Vout) and voltage
margins (Margin low and Margin high)
Configurable protection limits for OVP, input over
voltage, input under voltage, over current, on/off,
and temperature
Status monitor Vout, Iout, Vin, Temp, Power
good, and On/Off
Applications
Distributed power architectures
Intermediate bus voltage applications
Servers and storage applications
Network equipment
