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.
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.

The packages are mounted on the epoxy board (4 cm x 4 cm x 1.5 mm)
NOTE :
Permanent device damage may occur if the above

Ratings
are exceeded. Functional operation should be restricted to the
conditions as detailed in the operational sections data sheet. Exposure
to absolute maximum rating conditions for extended periods may affect
device reliability.

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.
