EL7562
Monolithic 2Amp DC-DC Step-Down
Regulator
The EL7562 is an integrated, synchronous step-down
regulator with output voltage adjustable from 1.0V to 3.8V. It
is capable of delivering 2A continuous current at up to 95%
efficiency. The EL7562 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 EL7562 is
available in a fused-lead 16 Ld QSOP package. With proper
external components, the whole converter fits into a less
than 0.5 in
2
area. The minimal external components and
small size make this EL7562 ideal for desktop and portable
applications.
The EL7562 is specified for operation over the 0°C to +70°C
temperature range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
