■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 pulseat 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.
