NJU7665 Series
SMALL PACKAGE VOLTAGE INVERTER
■ GENERAL DESCRIPTION
The NJU7665 series is a voltage inverter incorporated RC
oscillator, pre-buffer and power-MOS, which generates a
polarity-converted negative voltage from +1.5V to +5.5V.
The switching frequency is fixed by internal RC oscillator and the
following line-up of 3 version are available to select.
The NJU7665 series is in MTP-5 package and it is suitable for
battery use items and other portable items.
