The TPS60402DBVT is a charge-pump Voltage Inverter with fixed 20kHz operation. The device generates an unregulated negative output voltage from an input voltage ranging from 1.6 to 5.5V. The device is typically supplied by a pre-regulated supply rail of 5/3.3V. Due to its wide input voltage range, two or three NiCd, NiMH or alkaline battery cells, as well as one Li-Ion cell can also power them. Only three external 1µF capacitors are required to build a complete DC-DC charge-pump inverter. Additional board area and component count reduction is achieved by replacing the Schottky diode that is typically needed for start-up into load by integrated circuitry. The TPS6040x can deliver a maximum output current of 60mA with a typical conversion efficiency of greater than 90% over a wide output current range. TPS60400 comes with a variable switching frequency to reduce operating current in applications with a wide load range and enables the design with low-value capacitors.
