TEXAS INSTRUMENTS  TPS60403DBVT  DC/DC Adjustable Charge Pump Voltage Converter, 1.6V to 5.5V in, -1.6V to -5.25V/60 mA out, SOT-23-5

Product Overview

The TPS60403DBVT is a 60mA Charge Pump Voltage Inverter with fixed 250kHz operation, generates an unregulated negative output voltage from an input voltage ranging from 1.6 to 5.5V. The device is typically supplied by a preregulated 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. 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 TPS60403DBVT 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.
