Part Numbers
There are two different models in this series based
on different loop compensation for various types of
capacitor banks. These models are as follows:
VRNB-40A18B: Compensated for capacitor bank
utilizing 4-6 820uF Oscon capacitors.
VRNB-40A18M: Compensated for Oscon caps
but all output voltages are divided by 1.1 yielding
an effective range of 1.0 to 1.68V compatible with
the requirements for new Motorola
microprocessors.
