Typical unit

FEATURES

PRODUCT OVERVIEW

ꢀ

3.3 Volts DC ﬁxed output up to 50 Amps

Unique among quarter-brick DC/DC converters, the

HPQ series offers very high output current (up to

50 Amps) in an industry standard “quarter brick”

package requiring no heat sink. The HPQ series

delivers up to 165 Watts ﬁxed voltage output for

printed circuit board mounting. Wide range inputs

on the 2.3" x 1.45" x 0.39" converter are 36 to 75

Volts DC (48 Volts nominal), ideal for datacom and

telecom systems. The ﬁxed output voltage is regu-

lated to within 1ꢀ and may be trimmed within

10ꢀ of nominal output.

Advanced automated surface mount assembly

and planar magnetics deliver full magnetic and

optical isolation with Basic protection up to 2250

Volts. To power digital systems, the outputs offer

fast settling to current steps and tolerance of

higher capacitive loads. Excellent ripple and noise

shutdown, an external remote On/Off control may

use either positive or negative polarity. Remote

Sense inputs compensate for resistive line drops at

high currents.

Industry standard quarter brick 2.3" x 1.45" x

0.39" open frame package

ꢀ

Wide range 36 to 75 Vdc input voltages with 2250

Volt Basic isolation

A wealth of self-protection features avoid prob-

lems with both the converter and external circuits.

These include input undervoltage lockout and

overtemperature shutdown using an on-board tem-

perature sensor. Excessive overcurrents limit their

power using the “hiccup” autorestart technique

and the outputs may be short-circuited indeﬁnitely.

Additional safety features include output overvolt-

age protection and reverse conduction elimination.

The synchronous rectiﬁer topology offers high efﬁ-

ciency for minimal heat buildup and “no heat sink”

operation. The HPQ series is designed to meet full

safety certiﬁcations to UL/EN/IEC/CSA 60950-1 and

ꢀ

Double lead-free assembly and attachment for RoHS

standards

ꢀ

Up to 165 Watts total output power

ꢀ

High efﬁciency synchronous rectiﬁer topology

ꢀ

Stable no-load operation with no required external

components

ꢀ

Operating temperature range -40 to +85° C. with

no heat sink required

ꢀ

Designed to meet UL/EN 60950-1, CSA-C22.2 No.

60950-1, safety approvals

speciﬁcations assure compatibility to CPU’s, ASIC’s, RFI/EMI conducted/radiated emission compliance

programmable logic and FPGA’s. No minimum load

is required. For systems needing controlled startup/

Extensive self-protection, current limiting and shut

down features

to FCC part 15 class B.
