DESCRIPTION
The MB3778 is a dual switching regulator control IC. It has a two-channel basic circuit that controls PWM system
switching regulator power. Complete synchronization is achieved by using the same oscillator output wave.
This IC can accept any two of the following types of output voltage: step-down, step-up, or voltage inversion
(inverting voltage can be output to only one circuit). The MB3778’s low power consumption makes it ideal for use
in portable equipment.
