MB3775PFV Datasheet PDF - Fujitsu

●■LOW VOLTAGE DUAL PWM SWITCHING REGULATOR CONTROLLER

●The MB3775 is a dual pulse-width-modulation control circuit. It contains the basic circuits required for two PWM

●control circuits. Complete synchronization is obtained by using the same oscillator output waveform.

●This IC can provide following types of output voltage: step down, step up, and inverter. Power consumption is low, thus the MB3775 is ideal for use in high-efficiency portable equipment.

●■FEATURES

●• Wide supply voltage range: 3.6 V to 18 V

●• Low current consumption: 1.3 mA typical

●• Wide oscillation frequency range: 1 kHz to 500 kHz

●• On-chip timer latch short protection circuit

●• On-chip under voltage lockout protection

●• On-chip reference voltage: 1.28 V

●• Variable dead time provides control over total operating range.

●• Two types of packages (SOP-16pin : 1 type, SSOP-16pin : 1 type)

●■APPLICATIONS

●• LCD monitor/panel

●• Surveillance camera etc.
