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.
