EL7563
Monolithic 4 Amp DC/DC Step-Down Regulator
DATASHEET
FN7296 Rev 2.00 May 13, 2005
The EL7563 is an integrated, full-featured synchronous stepdown regulator with output voltage adjustable from 1.0V to 2.5V. It is capable of delivering 4A continuous current at up to 95% efficiency. The EL7563 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 EL7563 features power tracking, which makes the start-up sequencing of multiple converters possible.
