EL7556D
Integrated Adjustable 6 Amp
Synchronous Switcher
The EL7556D is an adjustable synchronous DC:DC
switching regulator optimized for a 5V input and 1.0V-3.8V
output. By combining integrated NMOS power FETS with a
fused-lead package, the EL7556D can supply up to 6A
continuous output current without the use of external power
devices or discrete heat sinks, thereby minimizing design
effort and overall system cost.
On-chip resistorless current sensing is used to achieve
stable, highly efficient, current-mode control. The EL7556D
also incorporates the VCC2DET function to directly interface
with the Intel P54 and P55 microprocessors. Depending on
the state of VCC2DET, the output voltage is internally preset
to 3.5V or a user-adjustable voltage using two external
resistors. In both internal and external feedback modes the
active-high PWRGD output indicates when the regulator
output is within ±10% of the programmed voltage. An on-
board sensor monitors die temperature (OT) for over-
temperature conditions and can be connected directly to
OUTEN to provide automatic thermal shutdown. Adjustable
oscillator frequency and slope compensation allow added
flexibility in overall system design.
The EL7556D is available in a 28-pin SO package and is
specified for operation over the full -40°C to +85°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.
