Регуляторы напряжения - Импульсные регуляторы LM2662M/NOPB

DC/DC VOLTAGE CONVERTER , ADJ, SOIC-8

The LM2662M/NOPB is a CMOS switched capacitor charge-pump Voltage Converter inverts a positive voltage in the range of 1.5 to 5.5V to the corresponding negative voltage. The LM2662 uses two capacitors to provide 200mA of output current without the size and EMI related to inductor based converters. With an operating current of only 300µA and operating efficiency greater than 90% at most loads, the LM2662 provides ideal performance for battery powered systems. The LM2662 may also be used as a positive voltage doubler. The oscillator frequency can be lowered by adding an external capacitor to the OSC pin. Also, the OSC pin may be used to drive the LM2662 with an external clock. For LM2662, a frequency control (FC) pin selects the oscillator frequency of 20/150kHz.
