  • TPS65631  -  This device doesn't integrate the AVDD rail, Vneg min down to -4.4V instead of -5.4V

Description

The TPS65632A is designed to drive AMOLED displays (Active Matrix Organic Light Emitting Diode) requiring three supply rails, VPOS, VNEG and AVDD. The device integrates a boost converter for VPOS, an inverting buck boost converter for VNEG and a boost converter for AVDD which are suitable for battery operated products. The digital control pin (CTRL) allows programming the negative output voltage in digital steps. The TPS65632A uses a novel technology enabling excellent line and load regulation.

Features

  • 2.9V to 4.5V Input Voltage Range
  • Fixed 4.6V VPOS Output Voltage
  • 0.5% Accuracy VPOS at 25°C to Approximately 85ºC
  • External Output Sense Pin for VPOS
  • Excellent Line Transient Regulation
  • Digitally Programmable VNEG, –1.4V to –5.4V
  • - 4V Default Value for VNEG
  • TPS65632 Selectable AVDD, 5.8V and 7.7V TPS65632A Fixed AVDD 7.7V
  • 300mA Output Current for VPOS and VNEG
  • Short Circuit Protection
  • Thermal Shutdown
  • 3 x 3mm 16 pin QFN package
