NOTES:

1. Refer to TB347 for details about reel specifications.

2. These 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). 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), refer to the ISL8117 product information page. For more information about MSL, refer to TB363.

1

CLKOUT

Clock signal output. The frequency of the clock signal is the switching frequency set by the resistor from RT to ground.

4

2

MOD/SYNC Dual function pin. Connect this pin to VCC5V to select Diode Emulation mode with pulse skipping at light-load. While

connected to ground or floating, the controller operates in PWM mode at light-load.

Connect this pin to an external clock for synchronization. The controller operates in PWM mode at light-load when

synchronized with an external clock.

3

PGOOD

Open-drain logic output used to indicate the status of output voltage. This pin is pulled down when the output is not within

±11% of the nominal voltage or the EN pin is pulled LOW.
