FEATURES

PRODUCT OVERVIEW



Lowest cost! Highest reliability!

Rarely, has a Series of low-power DC/DC converters

been deﬁned by both low cost and Murata’s quality

and reliability. Our new BST Series of dual-output

3W DC/DC’s achieves this “best-of-both-worlds”

status by implementing a proven circuit architecture

(170-ꢀ00kHz ﬂyback design) as a full, SMT-on-pcb

assembly (including surface-mount magnetics) that is

is a quick ꢀ00μsec, while output ripple and noise are

typically 7±mVp-p.



100% SMT-on-pcb, including magnetics

These rugged modules are fully encapsulated

with a thermally conductive potting compound that

contributes to their outstanding moisture/vibration

resistance and impressive MTBF. They operate over

the full –40 to +7±°C temperature range without der-



100% automatically assembled



Standard "DIP" package and pinouts



Fully isolated, 1000Vdc guaranteed



±±, ±1ꢀ or ±1± Volt outputs

truly 100% automatically assembled. Packaged in min- ating. All models have been thoroughly characterized



Choice of 3 wide-range inputs:

iature 1.ꢀ±" x 0.8", DIP-like plastic packages (UL94V-0

rated) and requiring no external components, BST

Series DC/DC’s bring true component-like convenience

to designers of today’s distributed power systems.

Output voltages are ±±, ±1ꢀ or ±1± Volts. Input

voltage ranges are 4.±-9V (“D±” models), 9-18V

(“D1ꢀ” models) or an ultra-wide 18-7ꢀV (“D48”

models). BST DC/DC’s are fully isolated (1000Vdc

guaranteed) and include input (pi type) and output

ﬁlters within their package. Output transient response

(electrically, mechanically and thermally), qualiﬁed

(including HALT), and EMI/EMC tested. Additionally,

they are certiﬁed to UL19±0, CSA ꢀꢀ.ꢀ No. 9±0 and

IEC9±0.

Murata’s BST Model 3W DC/DC’s are excellent

selections for telecom/datacom, computer and

process-control applications demanding small size,

low cost and high reliability. If required, their design

“ﬂexibility” allows for easy modiﬁcation to your

application-speciﬁc requirements.

“D48” Models

Since these are isolated DC/DC converters, their outputs are “ﬂoating.” Any

BST model may be conﬁgured to produce an output of 10V, ꢀ4V or 30V (for

±±V, ±1ꢀV or ±1±V models, respectively) by applying the load across the

+Output (pin 6) and –Output (pin 8), with either output grounded. The Common

(pins ± and 7) should be left open (unconnected). Minimum ꢀ0% loading is

recommended under these conditions.

Filtering and Noise Reduction

Physical

All BST 3 Watt DC/DC Converters achieve their rated ripple and noise speciﬁca-

tions without the use of external input/output capacitors. In critical applications,

input/output ripple and noise may be further reduced by installing electrolytic

capacitors across the input terminals and/or low-ESR tantalum or electrolytic

capacitors across the output terminals. Output capacitors should be con-

nected between their respective output pin (pins 6 and 8) and Common (pins ±

and 7) as shown in Figure ꢀ. The caps should be located as close to the power

converters as possible. Typical values are listed in the tables below. In many

applications, using values greater than those listed will yield better results.

➀ These power converters require a minimum 10% loading to maintain speciﬁed regulation.

Operation under no-load conditions will not damage these devices; however they may not

meet all listed speciﬁcations.

➁ The current limit inception point is dependent on the input voltage. Therefore, it is possible

to draw current beyond the rated capacity. Users should fully characterize their load conditions.
