SMT15E-12V SERIES
0.8 Vin to 3.63 Vin Single output
15 A Current rating Input voltage range: 10.0 Vdc - 14.0 Vdc Output voltage range: 0.8 Vdc - 3.63 Vdc Ultra high efficiency: 94% @ 12 Vin and 3.3 Vout Extremely low internal power dissipation Minimal thermal design concerns Designed in reliability: MTBF of 6,920,000 hours per Telcordia SR-332 Ideal solution where board space is at a premium or tighter card pitch is required Industry standard surface-mount footprint Available RoHS compliant
THE SMT15E-12 series are non-isolated dc-dc converters packaged in a single-inline footprint giving designers a cost effective solution for conversion from a 10 Vdc to 14 Vdc input to output voltages of 0.8 Vdc to 3.63 Vdc. The SMT15E-12 offers a wide outputs trim range, which allows maximum design flexibility and a pathway for future upgrades.
The SMT15E-12 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 SMT15E-12 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 10: Thermal reference points.
Case Temperature should not exceed 115C
Note 2
The Remote ON/OFF pin is referenced to ground.
Note 3
The SMT15E-12 features an `Active High' 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 SMT15E: Configuration Remote pin open circuit Remote pin pulled low [Von/off <.8V] Remote pin pulled high [Von/off >1.6V] Converter Operation Unit is ON Unit is OFF Unit is ON
Direction of Airflow
A an `Active Low' Remote ON/OFF version is also possible with this converter. Please consult the factory for details. Figure 10: Thermal Reference Points
Note 4
Thermal reference set up: Unit mounted on an edge card test board 203mm x 190mm. Test board mounted vertically. For test details and recommended set-up see Application Note 142.
Note 5
Max 60C for full load in still air. See Application Note 142 for a detailed thermal Derating. 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.
