General Description
The EL7563C is an integrated, full-featured synchronous step-down
regulator with output voltage adjustable from 1.0V to 2.5V. It is capa-
ble of delivering 4A continuous current at up to 95% efficiency. The
EL7563C 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 EL7563C 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 charac-
terization. The minimal external components and full functionality
make this EL7563C ideal for desktop and portable applications.
The EL7563C is specified for operation over the full -40°C to +85°C
temperature range.
