1% Output Accuracy 600kHz/1.2MHz PWM Step-Up
Regulator
ISL97519
The ISL97519 is a high frequency, high efficiency step-up
voltage regulator operated at constant frequency PWM mode.
With an internal 2.0A, 200mMOSFET, 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 <1µA of current and can operate
down to 2.3V input supply. These features, along with 1.2MHz
switching frequency, make it an ideal device for portable
equipment and TFT-LCD displays.
The ISL97519 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 +105°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 ISL97519. For more information on MSL please see
techbrief TB363.
