EL7564 NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ISL8024 Monolithic 4 Amp DC/DC Step-Down Regulator DATASHEET FN7297 Rev 3.00 May 9, 2005 The EL7564 is an integrated, full-featured synchronous stepdown regulator with output voltage adjustable from 1.0V to 3.8V. It is capable of delivering 4A continuous current at up to 95% efficiency. The EL7564 operates at a constant frequency pulse width modulation (PWM) mode, making external synchronization possible. Patented on-chip resistorless current sensing enables current mode control, which provides cycle-by-cycle current limiting, over-current protection, and excellent step load response. The EL7564 features power tracking, which makes the start-up sequencing of multiple converters possible.
