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.
