Renesas Electronics Corporation TFT-LCD Power Supply EL7586AILZ-T13

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 VsubON/sub and VsubLOGIC/sub generation, and a single negative LDO for VsubOFF/sub generation. The boost converter can be programmed to operate in either P-mode or PI-mode for improved load regulation.brbr 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. EL7586 also features an integrated start-up sequence for VsubBOOST/sub/VsubLOGIC/sub, VsubOFF/sub, then VsubON/sub or for VsubLOGIC/sub, VsubOFF/sub, VsubBOOST/sub, and VsubON/sub. The latter requires a single external transistor. The timing of the start-up sequence is set using an external capacitor.brbr EL7586A features an immediately-enabled VsubLOGIC/sub output which is independent of EN input. The VsubLOGIC/sub output will be switched off if a fault is detected and the power supply needs to be recycled to reset this condition.brbr Both the EL7586 and EL7586A are pin-compatible, come in the 20 Ld 4x4 QFN package, and are specified for operation over the -40°C to +85°C temperature range.
