Description
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 feedforward 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.
