Data Sheet
April 7, 2011
Rtrim is the external resistor in kΩ, and Vo is the desired
output voltage.
Table 1 provides Rtrim values required for some
common output voltages.
By using a ±0.5% tolerance trim resistor with a TC of
±25ppm, a set point tolerance of ±1.5% can be achieved
as specified in the electrical specification. The POL
Programming Tool available at
under the Design Tools section, helps determine the
required trim resistor needed for a specific output
voltage.

output voltage using an external resistor.
Remote Sense
The Micro TLynx
feature to minimize the effects of distribution losses by
regulating the voltage at the SENSE pin. The voltage
between the SENSE pin and VOUT pin must not
exceed 0.5V. Note that the output voltage of the module
cannot exceed the specified maximum value. This
includes the voltage drop between the SENSE and Vout
pins. When the Remote Sense feature is not being
used, connect the SENSE pin to the VOUT pin.

Startup into Pre-biased Output
The 5.5V Pico TLynx
prebiased output as long as the prebias voltage is 0.5V
less than the set output voltage. Note that prebias
operation is not supported when output voltage
sequencing is used.
Output Voltage Sequencing
The APTH012A0X modules include a sequencing
feature, EZ-SEQUENCE that enables users to
implement various types of output voltage sequencing in
their applications. This is accomplished via an
additional sequencing pin. When not using the
sequencing feature, either tie the SEQ pin to V
leave it unconnected.
