SMT05E Series | 5 A DC-DC Converter E Class Non-Isolated
SMT05E SERIES
0.75 Vin to 3.63 Vin Single output
5 A current rating Output voltage range: 0.75 Vdc to 3.63 Vdc Applications for 5 V or 3.3 V input POL converters High power density (191 W/in3) High efficiency - typically 94% for 5 Vin and 3.3 V out SMT POL converter that saves board space Industry standard footprint Remote ON/OFF Available RoHS compliant
THE SMT05E series are non-isolated SMT dc-dc converters packaged in an industry standard footprint giving designers a cost effective solution for conversion from either a 5 V or 3.3 V input to output voltages of 3.63 Vdc and 0.75 Vdc. The SMT05E offers a wide output range, which allows maximum design flexibility and a pathway for future upgrades. Local voltage conversion by the SMT05E series from existing 5 V or 3.3 V system voltages eliminates the need for redesign of existing power architectures when voltage requirements change. The SMT05E is designed for applications that include
distributed power, workstations, optical network and wireless applications. Implemented using state of the art surface mount technology and automated manufacturing techniques, the SMT05E offers compact size and efficiencies of up to 94%.

Note 1
Thermal reference is defined as the highest temperature measured at any one of the specified thermal reference points. See Figure 16: Thermal reference points.
Case Temperature Should Not Exceed 115C
Note 2
The Remote ON/OFF pin is referenced to ground.
Note 3
The SMT05E features a `Negative Logic' Remote ON/OFF operation. If not using the Remote ON/OFF pin, leave the pin open (the converter will be on). The Remote ON/OFF pin is referenced to ground. The following conditions apply for the SMT05E: Configuration Remote pin open circuit Remote pin pulled low Remote pin pulled high [Von/off >2.5 V] Converter Operation Unit is ON Unit is ON Unit is OFF
Direction of Airflow
A `Positive Logic' Remote ON/OFF version is also possible with this converter. To order please use part number SMT05E-05W3V3-R or SMT05E-05W3V3-RTJ.
Figure 16: Thermal Reference Points
Note 4
Thermal reference set up: Unit mounted on an edge card test board 203 mm x 190 mm. Test board mounted vertically. For test details and recommended set-up see Application Note 146.
Note 5
Max 75 C for full load in still air.
Note 6
For SMT05E-05W3V3 minimum operating voltage is 4.5 V, for Vo = 3.3 V
CAUTION: Hazardous internal voltages and high temperatures. Ensure that unit is accessible only to trained personnel. The user must provide the recommended fusing in order to comply with safety approvals.
