MB3769A
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.
High frequency oscillator (f = 1 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, C
L
= 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)
PLASTIC DIP 16-PIN
(DIP-16P-M04)
PLASTIC FPT 16-PIN
(FPT-16P-M06)
This device contains circuitry to protect the inputs against
damage due to high static voltages or electric fields.
However, it is advised that normal precautions be taken
to avoid application of any voltage higher than maximum
rated voltages to this high impedance circuit.
