Description

The EL7585AILZ stands for a multiple output regulators for utilize in all large panel, TFT-LCD applications. It features a single boost converter with combined 3.5A FET, two positive LDOs for VON and VLOGIC generation, and a single ne gative LDO for VOFF generation. The boost converter is able to be programmed to operate in either P-mode or PI-mo de for improved load regulation.The EL7585AILZ also combines fault protection for all four channels.The device is latc hed off until the input supply or EN is cycled when a fault is detected. This device also features an integrated start-up sequence for VBOOST, VOFF, then VON or for VOFF, VBOOST, and VON sequencing. The latter demands a single external transistor. The timing of the start-up sequence is set using an external capacitor.

Features of the EL7585AILZ are:(1)3.5A current limit FET options; (2)3V to 5V input; (3)up to 20V boost out; (4)1% regulation on all outputs; (5)programmable sequence delay; (6)fully fault protected; (7)thermal shutdown; (8)intern al soft-start; (9)20 Ld QFN packages; (10)Pb-free plus anneal available (RoHS compliant).

The absolute maximum ratings and electrical specifications(VDD = 5V, VBOOST = 11V, ILOAD = 200mA, VON = 15V, V OFF = -5V, VLOGIC = 2.5V, over temperature from-40°C to 85°C) of the EL7585AILZ can be summarized as:(1):VDR VP is 36V;(2):VDRVN is-20V;(3):VDD is 6.5V;(4):VDELB, VLX is 24V; (5):VDRVL is 6.5V;(6):storage temperature ranges from-65°C to +150°C;(7):ambient operating temperature is from-40°C to +85°C;(8):maximum continuous juncti on temperature is 125°C.Electrical specifications:(1):supply voltage is 3V min and 5.5V max;(2):quiescent current is 1.7mA typ and 2.5mA max;(3):oscillator frequency is 900kHz min,1000kHz typ and 1100kHz max;(4):boost output ranges from 5.5V to 20V;(5):reference voltage is 1.19V min,1.215V typ and 1.235V max when TA is 25°C;(6):switch leakage current is 10uA when VLX is 16V;(7):switch on-resistance is 160m,etc.
