FN7290.1

High Frequency PWM Step-Up Regulator

Features

The EL7512 is a high frequency, high efficiency step-up

DC:DC regulator operated at fixed frequency PWM mode.

With an integrated 1A MOSFET, it can deliver up to 600mA

output current at up to 90% efficiency. The adjustable

switching frequency is up to 1.2MHz, making it ideal for DSL

applications.

• 90% efficiency

• Up to 600mA I

OUT

< 18V

• 5V < V

OUT

• V > 2V

• Up to 1.2MHz adjustable frequency

• < 3µA shutdown current

When shut down, it draws <3µA of current. This feature,

along with the minimum starting voltage of 2V, makes it

suitable for portable equipment powered by one lithium ion

or 3 to 4 NiMH cells.

• Adjustable soft-start

• Low battery detection

The EL7512 is available in a 10-pin MSOP package, with

maximum height of 1.1mm. With proper external

components, the whole converter takes less than 0.25in

• Internal thermal protection

• 1.1mm max height 10-pin MSOP package

• Pb-Free available (RoHS compliant)

PCB space.

This device is specified for operation over the full -40°C to

+85°C temperature range.

Applications

• 3V to 5V, 12V, and 18V converters

• 5V to 12V and 16V converters

• TFT-LCD

NOTE: Intersil Pb-free 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.
