Feature Descriptions
Remote On/Off
The Austin Lynx™ SIP power modules feature an
On/Off pin for remote On/Off operation. If not using the
remote On/Off pin, leave the pin open (module will be On).
The On/Off pin signal (Von/off) is referenced to ground. To
switch the module on and off using remote On/Off, connect
an open collector pnp transistor between the On/Off pin and
the VI pin (see Figure 20).
During a logic-low when the transistor is in the Off state, the
power module is On and the maximum
Von/off generated by the module is 0.3V. The maximum
leakage current of the switch when Von/off = 0.3V and VI =
5.5V (Vswitch = 5.2V) is 10 µA. During a logic-high when the
transistor is in the active state, the power module is Off. Dur-
ing this state, Von/off = 2.5V to 5.5V and the maximum Ion/
off = 1mA.
Figure 20. Remote On/Off Implementation.
Output Voltage Set-Point Adjustment
(Trim)
Output voltage set-point adjustment allows the output volt-
age set point to be increased or decreased by connecting
either an external resistor or a voltage source between the
TRIM pin and either the VO pin (decrease output voltage) or
GND pin (increase output voltage).
For TRIM-UP using an external resistor, connect Rtrim-up
between the TRIM and GND pins (Figure 21). The value of
Rtrim-up defined as:
|DVout| is the desired output voltage set-point adjustment
Rbuffer (internal to the module) is defined in Table 1 for vari-
ous models.

Table 1. Austin Lynx™ Trim Values
Note: V
For example, to trim-up the output voltage of 1.5V
module (AXH010A0M) by 8% to 1.62V, Rtrim-up is
calculated as follows:
Figure 21. Circuit Configuration to trim-up output
For trim-down using an external resistor, connect Rtrim-
down between the TRIM and VOUT pins of the module
(Figure 22). The value of Rtrim-down is defined as:
Vout is the typical set point voltage of a module
|DVout| is the desired output voltage adjustment
Rbuffer (internal to the module) is defined in Table 3 for vari-
ous models
For example, to trim-down the output voltage of 2.5 V mod-
ule (AXH010G) by 8% to 2.3V, Rtrim-down is
calculated as follows:
