Description

The TPS60800-Q1 generates an unregulated negative output voltage from an input voltage ranging from 1.8V to 5.25V. The devices are typically supplied by a preregulated supply rail of 5V or 3.3V. As TPS60800-Q1 supports wide input voltage range, two or three NiCd, NiMH, or alkaline battery cells, as well as one Li-Ion cell can also power the device.

Only three external 1µF capacitors are required to build a complete DC-DC charge pump inverter. Assembled in a 6-pin SOT563 package, the complete converter can be built on a 40mm2 board area. 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 TPS60800-Q1 can deliver a maximum output current of 200mA with a typical conversion efficiency of greater than 90% over a wide output current range. TPS60800-Q1 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.
