OKI-T/36W-W40 Series
Selectable Output 36-Watt DOSA-SMT DC/DC Converters
Typical unit
PRODUCT OVERVIEW
The OKI-T/36W-W40 are non-isolated Point-of-
Load (PoL) DC/DC power converters for embedded
applications. The module is fully compatible with
Distributed-power Open Standards Alliance (DOSA)
industry-standard specifications (www.dosapower
.com).
The wide input range is 19 to 40 Volts DC. Power
output is 36 watts at Vout = 12Vdc. Based on fixed-
frequency synchronous buck converter switching
topology, the high power conversion efficient Point
of Load (POL) module features an On/Off control.
These converters also include under voltage lock
out (UVLO), output short circuit protection, over-
current and over temperature protections.
These units are designed to meet all standard
UL/EN/IEC 60950-1 safety certifications and RoHS-
6 hazardous substance compliance.
FEATURES
Non-isolated SMT PoL DC/DC power module
19-40Vdc input voltage range
Selectable output voltage 5.021-15.5Vdc
Up to 3 Amps output
Drives 1000 μF ceramic capacitive loads
High power conversion efficiency
Outstanding thermal derating performance
Over temperature and over current protection
On/Off control, positive or negative polarity
UL/EN/IEC 60950-1 safety (pending)
Industry-standard (DOSA) surface-mount package
RoHS-6 hazardous substance compliance

Specification Notes, Cont.:
(5) The On/Off Control Input should use either a switch or an open collector/open drain transistor referenced
to -Input Common. A logic gate may also be used by applying appropriate external voltages which do not
exceed +Vin.
(6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected
setting.
(7) Deleted.
(8) Output noise may be further reduced by adding an external filter. At zero output current, the output may
contain low frequency components which exceed the ripple specification. The output may be operated
indefinitely with no load.
(9) All models are fully operational and meet published specifications, including “cold start” at –40˚ C.
(10) Regulation specifications describe the deviation as the line input voltage or output load current is varied
from a nominal midpoint value to either extreme.
(11) Other input or output voltage ranges will be reviewed under scheduled quantity special order.
(12) Maximum PC board temperature is measured with the sensor in the center of the converter.
(13) Do not exceed maximum power specifications when adjusting the output trim.
(14) The maximum output capacitive loads depend on the the Equivalent Series Resistance (ESR) of the external
output capacitor and, to a lesser extent, the distance and series impedance to the load. Larger caps will
reduce output noise but may change the transient response. Newer ceramic caps with very low ESR may
require lower capacitor values to avoid instability. Thoroughly test your capacitors in the application. Please
refer to the Output Capacitive Load Application Note.
(15) Do not allow the input voltage to degrade lower than the input undervoltage shutdown voltage at all times.
Otherwise, you risk having the converter turn off. The undervoltage shutdown is not latching and will
attempt to recover when the input is brought back into normal operating range.
(16) The outputs are not intended to sink appreciable reverse current.
(17) “Hiccup” overcurrent operation repeatedly attempts to restart the converter with a brief, full-current output.
If the overcurrent condition still exists, the restart current will be removed and then tried again. This short
current pulse prevents overheating and damaging the converter. Once the fault is removed, the converter
immediately recovers normal operation.
Output Voltage Adustment
The output voltage may be adjusted over a limited range by connecting an
external trim resistor (Rtrim) between the Trim pin and Ground. The Rtrim
resistor must be a 1/10 Watt precision metal film type, ±1% accuracy or
better with low temperature coefficient, ±100 ppm/oC. or better. Mount the
resistor close to the converter with very short leads or use a surface mount
trim resistor.
In the tables below, the calculated resistance is given. Do not exceed the
specified limits of the output voltage or the converter’s maximum power
rating when applying these resistors. Also, avoid high noise at the Trim
input. However, to prevent instability, you should never connect any capaci-
tors to Trim.
