FN9261.5
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 a 2.0A typical switch current limit and 200mΩ
MOSFET, it can deliver 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 <1µA 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°C to +85°C temperature range.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials,
and 100% matte tin plate plus anneal (e3 termination finish,
which is 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.
3. For Moisture Sensitivity Level (MSL), please see device
information page for ISL97516. For more information on MSL
please see techbrief TB363.
