FN9261.2
600kHz/1.2MHz PWM Step-Up Regulator
The ISL97516 is a high frequency, high efficiency step-up
voltage regulator operated at constant frequency PWM
mode. With an internal 2.0A, 200m惟 MOSFET, it can deliver
up to 1A 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 <1碌A(chǔ) of current and can operate
down to 2.3V input supply. These features along with
1.2MHz switching frequency makes it an ideal device for
portable equipment and TFT-LCD displays.
The ISL97516 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擄C to +85擄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.
