EL7586A Datasheet Tft-lcd Power Supply

Manufacturer: Renesas

Overview: EL7586, EL7586A TFT-LCD Power Supply EL7586 NOT REMENDED FOR NEW DESIGNS REMENDED REPLACEMENT PART EL7586A DATASHEET FN9210 Rev 2.00 January 17, 2006 The EL7586 and EL7586A represent multiple output regulators for use in all large panel, TFT-LCD applications. Both feature a single boost converter with an integrated 2A FET, two positive LDOs for VON and VLOGIC generation, and a single negative LDO for VOFF generation. The boost converter can be programmed to operate in either P-mode or PI-mode for improved load regulation. Both EL7586 and EL7586A also integrate fault protection for all four channels. Once a fault is detected, the device is latched off until the input supply or EN is cycled.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

  • an integrated start-up sequence for VBOOST/VLOGIC, VOFF, then VON or for VLOGIC, VOFF, VBOOST, and VON. The latter requires a single external transistor. The timing of the start-up sequence is set using an external capacitor. EL7586A features an immediately-enabled VLOGIC output which is independent of EN input. The VLOGIC output will be switched off if a fault is detected and the power supply needs to be recycled to reset this condition. Both the EL7586 and EL7586A are pin-compatible, come in t.
