Specifications

Notes

1

The SMT12F features an ‘Active Low’ Remote ON/OFF operation. If you are

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 SMT12F:

Configuration

Converter Operation

Remote pin open circuit

Unit is ON

Remote pin pulled low

Unit is ON

Remote pin pulled high

Unit is OFF

An ‘Active High’ Remote ON/OFF version is also possible with this converter.

To order please place the suffix ‘R’ towards the end of the part number, e.g.

SMT12F-05W3V3RJ.

See Figures 1 and 2 for sample derating curves. For the full set of derating

curves see Application Note 165.

A 22 μF ceramic input capacitor may be required for test purposes only. See

SMT12F -05W3V3J

Part Number System with Options

Product Family

SMT = Surface Mount

Rated Output Current

12 = 12 Amps

Input Voltage

03 = 2.97 Vdc to 3.63 Vdc

05 = 3.0 Vdc to 5.5 Vdc

Type of Output

S = Single Fixed

W = Wide

Performance

F = Enhanced/Fast Transient

The ultra-wide output voltage trim range offers major advantages to users who select the

SMT12F. It is no longer necessary to purchase a variety of modules in order to cover different

output voltages. The output voltage can be trimmed in a range of 0.9 Vdc to 2.6 Vdc or 0.9

Vdc to 3.3 Vdc. When the SMT12F-05W3V3J converter leaves the factory the output has been

adjusted to the default voltage of 3.3 V. When the SMT12F-03W2V6J converter leaves the

factory the output has been adjusted to the default voltage of 2.6 V.

Output Voltage Adjustment of the SMT12F Series

Application Note 165 for further details.

4

An external output capacitor is required for basic operation. Required

capacitance is a minimum of 110 μF to meet the performance parameters.

This can be made up of any combination of 22 μF or 44 μF multi-layer

ceramic capacitors in the appropriate voltage rating.

5

Ripple and Noise is worst case measurement. Typical value is 26 mV pk-pk.

6

When Vin <4.5 V, Vout max = 2.5 V for model SMT12F-03W2V6.

7

TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special

request, please contact your local sales representative for details.
