FEATURES  
DESCRIPTIO  
■
Margin Voltage Precision <0.4%  
The LTC®2920 allows power supplies and power supply  
module output voltages to be precisely adjusted both up  
and down for automated PCB testing. The power supply  
output voltage is changed by sourcing or sinking current  
into the feedback node or voltage adjust pin of the power  
supply. This allows a system to test the correct operation  
of electrical components at the upper and/or lower power  
supply voltage limits specified for a given design (Power  
Supply “Margining”).

Single in 5-Pin ThinSOTTM (LTC2920-1)  
■
The LTC2920 uses a single resistor to set the voltage  
margining current. The margining current is adjustable  
over a 400:1 range. Precision margin currents can be  
supplied to within 0.6V of ground or VCC.  
■
Dual in 8-Pin MSOP (LTC2920-2)  
U
APPLICATIO S  
The LTC2920-1 is a single margining controller. The  
LTC2920-2 has two independently controllable margining  
channels.Eachchannelhasitsowncontrolpinandcurrent  
setting resistor. The LTC2920-2 can be used to symmetri-  
cally margin two power supplies, or asymmetrically mar-  
gin a single power supply.
