EL7564
Monolithic 4 Amp DC/DC Step-Down
Regulator
The EL7564 is an integrated, full-featured synchronous step-
down 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. A junction
temperature indicator conveniently monitors the silicon die
temperature, saving the designer time on the tedious
thermal characterization. The minimal external components
and full functionality make this EL7564 ideal for desktop and
portable applications.
The EL7564 is specified for operation over the -40°C to
+85°C temperature range.
