EL7515

High Frequency PWM Step-Up Regulator

The EL7515 is a high frequency, high efficiency step-up

DC:DC regulator operated at fixed frequency PWM mode.

With an integrated 1.4A MOSFET, it can deliver up to 600mA

output current at up to 92% efficiency. The adjustable

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

applications.

When shut down, it draws <1µA of current. This feature,

along with the minimum starting voltage of 1.8V, makes it

suitable for portable equipment powered by one lithium ion,

3 to 4 NiMH cells, or 2 cells of alkaline battery.

The EL7515 is available in a 10-pin MSOP package, with

maximum height of 1.1mm. With proper external

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.
