NOTES:

1. See 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), see the ISL8013A device information page. For more information about MSL, see TB363.

Pin Descriptions

PIN NUMBER

PIN NAME

DESCRIPTION

1, 2

VIN

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

3

VDD

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

5

EN

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.

7

PG

1ms timer output. At power-up or EN HI, this output is a 1ms delayed power-good signal for the output voltage.

4

SYNCH

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.

13, 14, 15

LX

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

11, 12

PGND

Power ground

9, 10

SGND

Signal ground

8

VFB

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.

6

NC

Pin 6 is used for ISL8013A production test only. It can be connected to GND for noise immunity in applications.

16

No connect pins.

Exposed Pad

The exposed pad must be connected to the SGND pin for proper electrical performance. Place as many vias as

possible under the pad connecting to SGND plane for optimal thermal performance.
