Datasheet ISL8117 Synchronous Step-Down PWM Controller The ISL8117 is a synchronous buck controller used to Features generate POL voltage rails and bias voltage rails for a Wide input voltage range: 4.5V to 60V wide variety of applications in industrial and general Wide output voltage range: 0.6V to 54V purpose segments. Its wide input and output voltage ranges make it suitable for telecommunication and Light-load efficiency enhancement after-market automotive applications. Low ripple Diode Emulation mode with pulse The ISL8117 uses the valley current modulation skipping technique to bring hassle-free power supply design Programmable soft-start with a minimal number of components and complete protection from unwanted events. Supports prebiased output with SR soft-start Programmable frequency: 100kHz to 2MHz The ISL8117 offers programmable soft-start and enable functions along with a power-good indicator External sync for ease of supply rail sequencing and other PGOOD indicator housekeeping requirements. In ideal situations, a complete power supply circuit can be designed with Forced PWM 10 external components and provide OV/OC/OT Adaptive shoot-through protection protections in a space conscious 16 Ld 4mmx4mm No external current sense resistor QFN or easy to assemble 6.4mmx5mm 16 Ld HTSSOP package. Both packages use an EPAD to Use lower MOSFET r DS(ON) improve thermal dissipation and noise immunity. Low Complete protection pin count, fewer external components, and default internal values makes the ISL8117 an ideal solution Overcurrent, overvoltage, over-temperature, for quick to market simple power supply designs. The undervoltage ISL8117 uses internal loop compensation and single Pb-free (RoHS compliant) resistor settings for other functions such as operating frequency and overcurrent protection. Its current Applications mode control with V feed-forward enables it to cover IN PLC and factory automation various applications even with fixed internal compensations. The unique DEM/Skipping mode at Amusement machines light-load dramatically lowers standby power Security surveillance consumption with consistent output ripple over Servers and data centers different load levels.
