Charge-pump converter inverts a positive voltage to corresponding negative voltage

This post is sponsored by Texas Instruments. A versatile charge-pump voltage converter which inverts a positive voltage in the range of 2.7V to 5.5V, to the corresponding negative voltage, the LM2776 has been introduced by Texas Instruments (TI). The LM2776 uses three low-cost capacitors to provide 200mA of output current without the cost, size, and electromagnetic interference (EMI) related to inductor-based converters. With an operating current of only 100µA and operating efficiency greater than 90% at most loads, the LM2776 provides ideal performance for battery-powered systems requiring a high power negative power supply. The compact LM2776 is housed a 6-pin SOT-23 package.
