DescriptionMB39A136 is a Current mode Nch/Nch synchronous rectification 2-channel DC/DC
buck converter IC. This IC has realized the high-speed response, high efficiency
and low ripple voltage by a current mode system. The ceramic condenser is able to
use. This product is the best for the downsizing of a set, by the adoption of the
small coil of high frequency operation and the small package.

DescriptionMB39C309 is a 7-channel DC/DC converter IC with two buck converter circuits, two
boost converter circuits, a inverter circuit, two buck boost converter circuits. DD1 to
DD6 channels adopt the current mode built in the phase compensation circuit. Highly
effective in a high frequency can be achieved in all channel with built-in Switching FETs.
In addition, MB39C309 is able to reduce the number of parts, as the two channel series
regulator is built in this IC. The MB39C309 is suitable for power supply of high
performance portable instruments powered by a 1-cell Li-ion rechargable battery.
