® EL7585 Data Sheet March 9, 2006 FN7345.2 TFT-LCD Power Supply The EL7585 represents a multiple output regulators for use in all large panel, TFT-LCD applications. It features a single boost converter with integrated 3.5A 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. The EL7585 also integrates fault protection for all four channels. .

® EL7585 Data Sheet March 9, 2006 FN7345.2 TFT-LCD Power Supply The EL7585 represents a multiple output regulators for use in all large panel, TFT-LCD applications. It features a single boost converter with integrated 3.5A 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. The EL7585 also integrates 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 device also features an integrated start-up sequence for VBOOST, VOFF, then VON or for VOFF, VBOOST, and VON sequencing. The latter requires a single external transistor. The timing of the start-up sequence is set using an external capacitor. The EL7585 is specified for operation over the -40°C to +85°C temperature range. Features • 3.5A current limit FET options • 3V to 5V input • Up to 20V boost out • 1% regulation on all outputs • VBOOST/VLOGIC-VOFF-VON or VLOGIC-VOFF-VBOOSTVON sequence control • Programmable sequence delay • Fully fault protected • Thermal shutdown • Internal soft-start • 20 Ld QFN packages • Pb-Free plus anneal available (RoHS Compliant) Ordering Information PART NUMBER EL7585ILZ www.DataSheet4U.com (Note) EL7585ILZ-T7 (Note) PART MARKING 7585ILZ 7585ILZ PACKAGE 20 Ld 4x4 QFN (Pb-free) 20 Ld 4x4 QFN (Pb-free) 20 Ld 4x4 QFN (Pb-free) TAPE & REEL 7” 13” PKG.

This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech Brief TB379. 2. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA Electrical Specifications PARAMETER SUPPLY VS IS CLOCK FOSC BOOST VBOOST VFBB VF_FBB VREF CREF DMAX ILXMAX ILEAK rDS(ON) Eff I(VFBB) ∆VBOOST/ ∆VIN ∆VBOOST/ ∆IBOOST ∆VBOOST/ ∆IBOOST VCINT_T Supply Voltage Quiescent Current VDD = 5V, VBOOST = 11V, ILOAD = 200mA, VON = 15V, VOFF = -5V, VLOGIC = 2.5V, over temperature from -40°C to 85°C, unless otherwise specified.
