ISL8117AFRZ-T Renesas Electronics 开关控制器

The ISL8117 is a synchronous buck controller used to
generate POL voltage rails and bias voltage rails for a
wide variety of applications in industrial and general
purpose segments. Its wide input and output voltage
ranges make it suitable for telecommunication and
after-market automotive applications.
The ISL8117 uses the valley current modulation
technique to bring hassle-free power supply design
with a minimal number of components and complete
protection from unwanted events.
The ISL8117 offers programmable soft-start and
enable functions along with a power-good indicator
for ease of supply rail sequencing and other
housekeeping requirements. In ideal situations, a
complete power supply circuit can be designed with
10 external components and provide OV/OC/OT
protections in a space conscious 16 Ld 4mmx4mm
QFN or easy to assemble 6.4mmx5mm 16 Ld
HTSSOP package. Both packages use an EPAD to
improve thermal dissipation and noise immunity. Low
pin count, fewer external components, and default
internal values makes the ISL8117 an ideal solution
for quick to market simple power supply designs. The
ISL8117 uses internal loop compensation and single
resistor settings for other functions such as operating
frequency and overcurrent protection. Its current
mode control with VIN feed-forward enables it to cover
various applications even with fixed internal
compensations. The unique DEM/Skipping mode at
light-load dramatically lowers standby power
consumption with consistent output ripple over
different load levels.
