EL7516

600kHz/1.2MHz PWM Step-Up Regulator

DATASHEET

The EL7516 is a high frequency, high efficiency step-up

voltage regulator operated at constant frequency PWM

mode. With an internal 1.5A, 200m

 MOSFET, it can deliver

up to 600mA output current at over 90% efficiency. The

selectable 600kHz and 1.2MHz allows smaller inductors and

faster transient response. An external compensation pin

gives the user greater flexibility in setting frequency

compensation allowing the use of low ESR Ceramic output

capacitors.

When shut down, it draws <10µA of current and can operate

down to 2.5V input supply. These features along with

1.2MHz switching frequency makes it an ideal device for

portable equipment and TFT-LCD displays.

The EL7516 is available in an 8 Ld MSOP package with a

maximum height of 1.1mm. The device 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.
