DESCRIPTION

The MB3759 is a control IC for constant-frequency pulse width modulated switching regulators.

The IC contains most of the functions required for switching regulator control circuits. This reduces both the component count and assembly work.

FEATURES

• Drives a 200 mA load

• Can be set to push-pull or single-end operation

• Prevents double pulses

• Adjustable dead-time

• Error amplifier has wide common phase input range

• Built in a circuit to prevent misoperation due to low power supply voltage.

• Built in an internal 5 V reference voltage with superior voltage reduction characteristics
