RIK0039A


The RIK0039A consists of a single 40V Buffer board. It is used in the fixture when voltages other than what can be provided by a tester resource are required. It is configured to be used either with an active or passive carrier.

Top View:



The 40V buffer board consists of 2 independent voltage multipliers. Each voltage multiplier will multiply an input voltage by 4X, up to 40V out. The multipliers can be disabled (set to approximately 0V) through the /E line, or disconnected through the /EO line. In addition, voltage and current monitors are provided.

** SX1xxx enables power where X = number of module slot, x = don't care

SX0xxx disables power where X = number of module slot, x = don't care
SXx1xx enables outputs where X = number of module slot, x = don't care
SXx0xx disables outputs where X = number of module slot, x = don't care


Warning! Do note use Cbits to enable and disable voltages when using this module on a Smart Carrier.

Performance:
Vout = Vin X 4
Max Vout = 40V typical
Imax = 9mA typical up to 30V, 3.5mA typical to 40V.

Bench Top DC Voltage Requirements:
