LC020 Single-Output Series Power Module:
Feature Descriptions (continued)
Remote On/Off
Two remote on/off options are available. Positive logic remote on/off turns the module on during a logic high volt-
age on the REMOTE ON/OFF pin, and off during a logic low. Negative logic device code suffix of “1,” remote on/off
turns the module off during a logic high and on during a logic low.
To turn the power module on and off, the user must supply a switch to control the voltage between the on/off termi-
nal and the VI(–) terminal (Von/off). The switch can be an open collector or equivalent (see Figure 19). A logic low is
Von/off = –0.7V to 1.2 V. The maximum Ion/off during a logic low is 1 mA. The switch should maintain a logic low volt-
age while sinking 1 mA.
During a logic high, the maximum Von/off generated by the power module is 6 V. The maximum allowable leakage
current of the switch at Von/off = 6 V is 50 A.
The module has internal capacitance to reduce noise at the ON/OFF pin. Additional capacitance is not generally
needed and may degrade the start-up characteristics of the module.

Output Voltage Adjustment
Output voltage trim allows the user to increase or decrease the output voltage set point of a module. This is accom-
plished by connecting an external resistor between the TRIM pin and either the VO(+) or VO(–) pins. With an exter-
nal resistor between the TRIM and VO(+) pins (Radj-down), the output voltage set point (VO, adj) decreases. With an
external resistor between the TRIM pin and VO(–) pin (Radj-up), VO,adj increases.
The following equations determine the required external resistor value to obtain an output voltage change of
