The SMT15E-12M significantly extends current non-isolated dc-dc
converter power management features by integrating a program-
mable active DC output control function. During product develop-
ment, the converter’s voltage set-point can be programmed – via
the built-in I2C™ interface – to a very high degree of accuracy,
and the active control function will maintain this setting very pre-
cisely during normal operation, by automatically compensating
for
different load conditions. The same function is used when
performing voltage margining during production test, to ensure
accurate results and prevent devices being over-stressed. Each
converter is supplied pre-programmed to standard default values
stored in non-volatile memory and only requires additional
programming by customers if they wish to change an operational
function.

Notes
1
The SMT15E-12M features a ‘Positive 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 SMT15E-12M:
Configuration
Remote pin open circuit
Remote pin pulled low [Von/off <0.8 V]
Remote pin pulled high [Von/off >1.6 V]
Converter Operation
Unit is ON
Unit is OFF
Unit is ON

A ‘Negative Logic’ Remote ON/OFF version is also possible with this converter.
To order please place the Suffix ‘-R’ at the end of the model number, e.g.
SMT15E-12M001-R.
To avoid over-shoot on start-up the appropriate trim resistor must be placed
on the trim pin. See Figure 3 on page 3.
Output voltage setpoint is set to 1.8 V. To change the nominal setpoint value
the unit will have to be reprogrammed and in addition an appropriate trim
resistor placed on the trim pin.
An evaluation kit is available to demonstrate the functionality of the SMT15E-
12M, including the I
2
C interface capability. To apply for an evaluation kit you
need to fill out an on-line request form.
