Power Good
The LGA C modules have a power good indicator output. This output pin uses positive logic and is open-
collector. Also, the power good output is able to sink 10 mA.
When the output of the module is within ±10% of the nominal set point, the Power Good pin can be pulled
high. Note that Power Good should not be pulled higher than the following conditions:
Current Sink Capabilities
The LGA C series of dc-dc converters is able to current sink as well as current source. The EPD operates
over the full output current range at any specified output voltage. This feature allows the LGA C to fit into
any voltage termination application.
Setting Output Voltage
The output of the module can be adjusted from 0.59 V to 5.1 V. This is accomplished by connecting an
external resistor between Trim and -Sense as shown in Figure 5 and graphed in Figure 8 or by driving the
Trim pin with an external voltage as shown in Figure 6. High accuracy setpoints can be achieved with the
use of a potentiometer as shown in Figure 7.
