Switching Regulator Controller

MB3778

■ 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.

■ FEATURES

• Wide input voltage range : 3.6 V to 18 V

• Low current consumption : 1.7 mA typ. operation, 10 µA max. stand-by

• Wide oscillation frequency range:1 kHz to 500 kHz

• Built-in timer latch short-circuit protection circuit

• Built-in under-voltage lockout circuit

• Built-in 2.46 V reference voltage circuit : 1.23 V output can be obtained from R^Tterminal

• Variable dead-time provides control over total range

• Built-in stand-by function: power on/off function
