MPDTH***60 Series
Adjustable Non-isolated 10-Amp
POLA DC/DC Converters
DESCRIPTION
The MPDTH series non-isolated DC/DC power modules are small in size but big
on performance and flexibility. Their high output current, compact footprint and
industry-leading features offer system designers versatile modules for powering
complex multi-processor digital systems. Standard inputs are 3.3V., 5V. or 12
Volts DC nominal.
Typical units
FEATURES
Compatible to Point-of-Load Alliance (POLA) Specifications
Surface-mount or through-hole small footprint package
Three user-selectable output voltage ranges covering 0.8V
to 5.5V
Outline dimensions less than one square inch
3.3V, 5V and 12 Vdc nominal inputs
High efficiency up to 94% typical
Tracking input for sequenced startup/shutdown
Sense input for load accuracy compensation
Outstanding thermal performance and derating
-40 to +85 degrees Celsius operating range
Extensive self-protection, voltage limits and short circuit
features
On/Off control, trim, margin controls and pre-bias start-up
functions
Two mounting styles are offered, either a pinned through-hole model with
slightly lower height or a surface mount model, both with identical length and
width. Respective models all share the same pinout and comply with the POLA
DC/DC converter standard.
The output voltage is adjustable in three ranges from 0.8 V. to 5.5 V and can
be set with a single external resistor. Margin controls provide a fixed step to
the output voltage either 5% up or down. The series also includes Auto-Track
sequencing, enabling modules to track each other’s output voltage in multi-
powered systems during power-up and power-down.
Other operating features include a remote on/off control and the ability to start
up into an existing (prebias) output voltage. Extensive self-protection features
include input under-voltage lockout (UV), output short circuit protection and
output overcurrent shutdown (OC) using an automatic restart. All models meet
RoHS6 hazardous substance compliance.

Notes:
1. Murata Power Solutions strongly recommends an external fuse, F1. Fuse rating = 2 x Iin max.
2. Consider using diode D1 to blow the fuse in case of reversed polarity.
3. C1: 330μF/25V, aluminum electrolytic capacitor, required for MPDTH03060, 05060 models.
C1: 560μF/25V, aluminum electrolytic capacitor, required for MPDTH12060 models.
4. Track input is referred to ground.
5. See trim information for RSet.
