EL7512
Data Sheet
High Frequency PWM Step-Up Regulator
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.
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.
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 2
PCB space.
This device is specified for operation over the full -40°C to
+85°C temperature range.

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.
