NOTES:

1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.

2. These Intersil 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). Intersil 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), please see device information page for ISL8013A. For more information on MSL please

see techbrief TB363.

DESCRIPTION

Input supply voltage. Connect a 10µF ceramic capacitor to power ground.

Input supply voltage for the analog circuitry. Connect to VIN pin.

Regulator enable pin. Enable the output when driven to high. Shut down the chip and

discharge output capacitor when driven to low. Do not leave this pin floating.

1ms timer output. At power-up or EN HI, this output is a 1ms delayed Power-Good signal

for the output voltage.

Mode Selection pin. Connect to logic high or input voltage VDD for PWM mode. Connect

to logic low or ground for PFM mode. Connect to an external function generator for

synchronization with the negative edge trigger. Do not leave this pin floating.

Switching node connection. Connect to one terminal of the inductor.

Power ground

Signal ground.

Buck regulator output feedback. Connect to the output through a resistor divider for

adjustable output voltage. For 0.8V output voltage, connect this pin to the output.

No connect.

The exposed pad must be connected to the SGND pin for proper electrical performance.

Place as much vias as possible under the pad connecting to SGND plane for optimal

thermal performance.
