TPS60403DBVR - TI Function Overview

The TPS60403DBVR is a 60mA Charge Pump Voltage Inverter with fixed 250kHz operation. This device generates an unregulated negative output voltage from an input voltage ranging from 1.6 to 5.5V. It is typically supplied by a pre-regulated supply rail of 5 or 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. The TPS60403 can deliver a maximum output current of 60mA with a typical conversion efficiency of greater than 90% over a wide output current range.
Inverts input supply voltage
Only three small 1µF ceramic capacitors needed
65µA Typical device quiescent current
Integrated active Schottky-diode for start-up into load
Green product and no Sb/Br
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.
