MB39C026 Evaluation Board
The MB39C026 is a two channels power supply IC. It consists of one channel
DC/DC Converter and one channel LDO regulator. The DC/DC converter has fast
line transient response and load regulation with current mode control topology.
Moreover, the integrated LDO provides an auxiliary output supply for noise
sensitive circuit.

1. Description
* CH1 Remark:
Maximum Output voltage is limited by the input voltage (VIN). The maximum
voltage CH1 could reach is 0.5V less than VIN.
# CH2 Remark:
The CH2 output voltage is limited by input voltage (VIN). The CH2 dropout of
MB39C026G is Vdrop. Thus the minimum input voltage should be Vdrop above
the CH2 output. Vdrop is 0.2V(Typ).
