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 product information page for ISL78213 . For more information on MSL, please see tech brief 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. Shutdown 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.
