MB3778 Datasheet | Fujitsu Semiconductor Limited

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27203-6E ASSP Switching Regulator Controller MB3778 s DESCRIPTION The MB3778 is a dual switching regulator control IC. It has a two-channel basic circuit that controls PWM system switching regulator power. plete 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. s Features - - - - - - - - Wide input voltage range : 3.6 V to 18 V Low current consumption : 1.7 mA typ. operation, 10 µA...
