EL7563C

Monolithic 4 Amp DC:DC Step-down Regulator

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.
