Product Overview
The LM2660M/NOPB is a switched capacitor voltage converter operates from a wide 1.5V to 5.5V supply voltage, the LM2660 uses two capacitors to provide 100mA of output current, without the size and EMI related to inductor-based converters. With an operating current of only 120µA and operating efficiency greater than 90% at most loads, the versatile unregulated switched capacitor inverter or doubler converter provides ideal performance for battery-powered systems and can be operated directly in parallel to lower output impedance, thus providing more current at a given voltage. The FC pin selects between a nominal 10KHz or 80KHz oscillator frequency. The oscillator frequency can be lowered by adding an external capacitor to the OSC pin. Through these methods, output ripple frequency and harmonics may be controlled. Additionally, the converter may be configured to divide a positive input voltage precisely in half. In this mode, input voltages as high as 11V may be used.
- Inverts or doubles input supply voltage
- 6.5ohm typical output resistance
- 88% typical conversion efficiency at 100mA
- 10/80KHz selectable oscillator frequency
- Optional external oscillator input
Applications
Power Management, Communications & Networking, Computers & Computer Peripherals, Consumer Electronics
Warnings
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
