The SMT06C series is a new high density open-frame, non-isolated converter for space sensitive

applications. Each model has a wide input range (4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8 Vdc)

and offers a wide 0.9 Vdc to 5.0 Vdc output voltage range with a 6 A load. An external resistor

adjusts the output voltage from its pre-set value of 0.9 V to any value up to the 5 V maximum.

Typical efficiencies for the models are 89% for the 5 V input version and 91% for the 12 V input

version. The series offers remote ON/OFF and overcurrent protection as standard. With full

international safety approvals including EN60950 and Ul/cUL60950, the SMT06C reduces

compliance costs and time to market.

All specifications are typical at nominal input Vin = 12 V, full load at 25 °C unless otherwise stated
