Single/Dual Power Supply

Margining Controller

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 ThinSOT^TM(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 V_CC.

■

Dual in 8-Pin MSOP (LTC2920-2)

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.
