NJU7662

The NJU7662 is designed as a voltage converter incorporated CR oscillator, voltage level shifter and power MOS, which generates a polarity-converted negative voltage or twofold voltage of an operating voltage ranging from +1.5V to +10V. The application circuit of negative voltage converter requires only two capacitors and positive twofold voltage converter requires two capacitors, two resistors and one diode as external components.

NJU7662 has nine features. (1) Polarity converted negative voltage output. (2) Twofold positive voltage output. (3) Operating voltage +4.5V to +20.0V. (4) High efficiency voltage conversion rate 99.9%. (no load, negative voltage converter). (5) High efficiency power conversion rate 96%. (negative voltage converter). (6) Cascade connection available. (7) Few external components. (8) Package outline DIP / DMP 8. (9) CMOS technology. That are all the main features.

Some absolute maximum ratings have been concluded into several points of NJU7662 as follow. (1) Its supply voltage is 22V. (2) Its input voltage is from -0.3V to V++0.3 at V+<7V and would be V+-7V to (V+)+0.3V at V+>7V. (3) Its power dissipation is 500mW for DIP8 and 300mW for DMP8. (4) Its operating temperature range is from -40°C to +85°C. (5) Its storage temperature range is from -65°C to +150°C.
