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.

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: 470μF/25V, aluminum electrolytic capacitor, required for MPDTH03010, 05010 models.

C1: 560μF/25V, aluminum electrolytic capacitor, required for MPDTH12010 models.

4. Track input is referred to ground.

5. See trim information for RSet.
