FN7339.1

Integrated Adjustable 6 Amp

Synchronous Switcher

Features

• Improved temperature and voltage ranges

• 6A continuous load current

• Precision internal 1% reference

• 1.0V to 3.8V output voltage

• Internal power MOSFETs

• >90% efficiency

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.

• Synchronous switching

• Adjustable slope compensation

• Over-temperature indicator

• Pulse-by-pulse current limiting

• Operates up to 1MHz

• 1.5% typical output accuracy

• Adjustable oscillator with sync

• Remote enable/disable

• Intel P54- and P55-compatible

• VCC2DET interface

• Internal soft-start

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.

• Pb-free plus anneal available (RoHS compliant)

Applications

• PC motherboards

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
