DESCRIPTION

POS VCOM amplifier non-inverting input

RSET DCP sink current adjustment pin. Connect a resistor between this pin and GND to set the resolution of DCP output voltage.

VOUT VCOM amplifier output

NEG VCOM amplifier inverting input

VDIV

NC

Voltage detector threshold. Connect to the center of a resistive divider between VIN and GND.

Not connected

RESET Voltage detector reset output

NC Not connected

CD2 Voltage detector rising edge delay. Connect a capacitor between this pin and GND to set the rising edge delay.

NC Not connected

SS Boost converter soft-start. Connect a capacitor between this pin and GND to set the soft-start time.

COMP Boost converter compensation pin. Connect a series resistor and capacitor between this pin and GND to optimize transient

response and stability.

FREQ Boost converter frequency select. Pull to logic high to operate boost at 1.2MHz. Connect this pin to GND to operate boost at

600kHz.

VIN IC input supply. Connect a 0.1µF decoupling capacitor close to this pin.

LX AVDD boost converter switching node

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 ISL97649B. For more information on MSL please see Tech Brief TB363.
