ISL8117DEMO4ZIntersil's ISL8117 is the first 60V sync buck controller able to bypass the intermediate step-down conversion stage traditionally employed in industrial applications. The controller’s low duty cycle enables the direct step-down conversion from 48V to a 1V POL, making it possible for you to reduce system complexity and solution cost in a variety of applications.The easy-to-use ISL8117 offers a cost-effective and reliable alternative for applications where Vout to Vin ratio is low.


  • Wide input voltage range: 4.5V to 60V Wide output voltage range: 0.6V to 54V Light-load efficiency enhancement Low ripple diode emulation mode with pulse skipping Programmable soft-start Supports prebiased output with SR soft-start Programmable frequency: 100kHz to 2MHz External sync PGOOD indicator Forced PWM Adaptive shoot-through protection No external current sense resistor Use lower MOSFET rDS(ON) Functional pins with default design values (ISL8117A) EN, RT, SS/TRK, MOD/SYNC, LGATE/OCS Complete protection Overcurrent, overvoltage, over-temperature, undervoltage Pb-free (RoHS compliant)
