Feature Descriptions
current-limiting circuitry and can endure current
limiting continuously. At the point of current-limit
inception, the unit enters hiccup mode. If the unit is
not configured with auto–restart, then it will latch off
following the over current condition. The module can
be restarted by cycling the dc input power for at least
one second or by toggling the remote on/off signal for
at least one second. If the unit is configured with the
auto-restart option (4), it will remain in the hiccup
mode as long as the overcurrent condition exists; it
operates normally, once the output current is brought
back into its specified range. The average output
current during hiccup is 10% I
Output Voltage Programming
Trimming allows the output voltage set point to be
increased or decreased, this is accomplished by
connecting an external resistor between the TRIM pin
and either the V

Voltage.
Connecting an external resistor (R
the TRIM pin and the Vo(-) (or Sense(-)) pin
decreases the output voltage set point. To maintain
set point accuracy, the trim resistor tolerance should
be ±1.0%.
The following equation determines the required
external resistor value to obtain a percentage output
voltage change of Δ%
For output voltage: 1.2V to 12V
Where
For example, to trim-down the output voltage of 2.5V
module (KW020A0G/G1) by 8% to 2.3V, Rtrim-down
is calculated as follows:

KW010/015/020/025 Series Power Modules:
Connecting an external resistor (R
TRIM pin and the V
the output voltage set point. The following equations
determine the required external resistor value to
obtain a percentage output voltage change of Δ%:
For output voltage: 1.5V to 12V
For output voltage: 1.2V
Where
For example, to trim-up the output voltage of 1.2V
module (KW025A0P/P1) by 5% to 1.26V, R
calculated is as follows:
Alternative voltage programming for output
voltage: 1.2V (-V Option)
An alternative set of trimming equations is available
as an option for 1.2V output modules, by ordering the
–V option. These equations will reduce the resistance
of the external programming resistor, making the
impedance into the module trim pin lower for
applications in high electrical noise applications.
Where
For example, to trim-up the output voltage of 1.2V
module (KW025A0P/P1-V) by 5% to 1.26V, R
calculated is as follows:
The value of the external trim resistor for the optional
–V 1.2V module is only 20% of the value required with
the standard trim equations.
