BALANCE CONTROLLER
May 27, 1999
TYPICAL APPLICATIONS (cont.)
Balanced Current Controller Utilizing EZ1087 Series
EZ1900
Voltage Select
Slave Mode Operation V_M = V_OUT of Master
V_M = V_REF (1 + R4/R3) + I_ADJ R4
Non-Slave Mode, V_S = V_OUT of Slave
V_S = V_REF (1 + (R2 + 3Ω) / R1) + I_ADJ (R2 + 3Ω)
R_SENSE Select
R_SENSE Select; Typical selection can be
(50mV to 100mV) / (Total I_OUT / 2).
Trace resistance of 10mΩ and above can easily accomodate value
required.
Balanced Current Controller Utilizing EZ1580 Series
Voltage Select
Slave Mode Operation V_M = V_OUT of Master
V_M = V_REF (1 + R4/R3) + I_ADJ R4
Non-Slave Mode, V_S = V_OUT of Slave
V_S = V_REF (1 + (R2 + 3Ω) / R1) + I_ADJ (R2 + 3Ω)

R_SENSE Select
R_SENSE Select (100mV Min) / (Total I_OUT / 2)
The EZ1580 series requires R_SENSE voltage to be less than 100mV.
Trace resistance can easily accomodate value required.
