MB3769A

■ DESCRIPTION

The Fujitsu MB3769A is a pulse-width-modulation controller which is applied to fixed frequency pulse modulation

technique. The MB3769A contains wide band width Op-Amp and high speed comparator to construct very high

speed switching regulator system up to 700 kHz. Output is suitable for power MOS FET drive owing to adoption

of totem pole output.

The MB3769A provides stand-by mode at low voltage power supply when it is applied in primary control system.

■ FEATURES

• High frequency oscillator (f = 1 kHz to 700 kHz)

• On-chip wide band frequency operation amplifier (BW = 8 MHz Typ)

• On-chip high speed comparator (td = 120 ns Typ)

• Internal reference voltage generator provides a stable reference supply (5 V ± 2%)

• Low power dissipation (1.5 mA Typ at standby mode, 8 mA Typ at operating mode)

• Output current ± 100 mA (± 600 mA at peak)

• High speed switching operation (tr = 60 ns, tf = 30 ns, CL = 1000 pF Typ)

• Adjustable Dead-time

• On-chip soft start and quick shut down functions

• Internal circuitry prohibits double pulse at dynamic current limit operation

• Under voltage lock out function (OFF to ON: 10 V Typ, ON to OFF: 8 V Typ)

• On-chip output shut down circuit with latch function at over voltage

• On-chip Zener diode (15 V)

• One type of package (SOP-16pin : 1 type)

■ APPLICATIONS

• Power supply module

• Industrial Equipment

• AC/DC Converter

etc.
