FEATURES High efficiency: 90.5% 15V/4.4A Size: 33.0 x 22.9 x 9.5 mm (1.30x0.90x0.37) Industry standard footprint and pinout Fixed frequency operation SMD and through-hole versions Input UVLO and OVP OTP and output OCP, OVP Output voltage trim: -15%, +10% Monotonic startup into normal and pre-biased loads 2250V isolation and basic insulation No minimum load required No negative current during power or enable on/off ISO 9001, TL 9000, ISO 14001, QS 9000, OHSAS18001 certified manufacturing facility UL/cUL 60950 (US & Canada) recognized th Delphi Series V48SR, 1/16 Brick 66W DC/DC Power Modules: 48V in, 15V, 4.4A out th The Delphi Series V48SR, 1/16 Brick, 48V input, single output, OPTIONS isolated DC/DC converter, is the latest offering from a world leader in SMD pins power systems technology and manufacturing Delta Electronics, Inc. Positive remote On/Off This product family provides up to 66 watts of power or 25A of output OTP and output OVP, OCP mode th current (1.8V and below) in an industry standard 1/16 brick form factor (auto-restart or latch) (1.30 x 0.90). The 15V output offers one of the highest output currents available and provides up to 90.5% efficiency at full load. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions. All modules are protected from abnormal input/output voltage, APPLICATIONS current, and temperature conditions. For lower power needs with the 15V Optical Transport output, but in a similar small form factor, please check out Delta S48SP Data Networking (36W or 15V/2.3A) and S48SE (17W or 15V/1A) series standard DC/DC Communications modules.
