Adjustable Output 3 and 5-Amp DOSA-SMT DC/DC Converters

Murata Power Solutions 

OKY-T/3,T/5-D12 Series

Adjustable Output 3 and 5-Amp DOSA-SMT DC/DC Converters

Output Capacitive Load

These converters do not require external capacitance added to achieve

rated specifications. Users should only consider adding capacitance to reduce

switching noise and/or to handle spike current load steps. Install only enough

capacitance to achieve noise objectives. Excess external capacitance may

cause regulation problems, degraded transient response and possible oscilla-

tion or instability.

The maximum rated output capacitance and ESR specification is given for a

capacitor installed immediately adjacent to the converter. Any extended output

wiring or smaller wire gauge or less ground plane may tolerate somewhat

higher capacitance. Also, capacitors with higher ESR may have a larger capaci-

tance. What counts here is the instantaneous maximum output current during

power-on charge-up and switching currents under load. Excessive current will

trip the overcurrent detection and shut off the converter.

Product Label

Because of the small size of these products, the product label contains a

character-reduced code to indicate the model number and manufacturing date

code. Not all items on the label are always used. Please note that the label dif-

fers from the product photograph on page 1. Here is the layout of the label:

The manufacturing date code is four characters:

First character – Last digit of manufacturing year, example 2009

Second character – Month code (1 through 9 and O through D)

Third character – Day code (1 through 9 = 1 to 9, 10 = O and

11 through 31 = A through Z)
