DESCRIPTION
Logic buck supply voltage. This is also the analog supply from which the VL is generated. Needs at
least 1μF bypassing.
Logic buck boot strap pin. Generate the gate drive voltage for the N-Channel MOSFET by connecting
a 1μF cap to the switching node LXL1, 2.
Logic buck switching node. Source of the high side internal power N-Channel MOSFET for the Buck.
Logic buck ground pin.
Buck compensation pin. An RC network is recommended. Increase R for better transient response at
the expense of stability.
Logic buck feedback pin. High impedance input to regulate at 1.215V.
5.25V internal regulator output. Bypass with a 4.7μF capacitor. Ref voltage is generated from VL.
Reference voltage output. Bypass with a low valued capacitor for transients - recommend 220nF.
Should not be greater than 5 times CDEL capacitor to ensure correct start-up sequence.
Negative charge pump feedback pin. High impedance input to regulate to 0.203V.
Negative charge pump supply voltage. Can be the same as or different from A VDD.
Negative charge pump driver output.
Charge pump ground pin.
Charge pump capacitor 1, positive connection.
Charge pump capacitor 1, negative connection.
Charge pump capacitor 2, positive connection.
Charge pump capacitor 2, negative connection.
Positive charge pump supply. Can be the same as or different from A VDD.
Positive charge pump feedback pin. High impedance input to regulate at 1.215V
V ON charge pump output.
High voltage switch control output. V ON slice output.
Lower reference voltage for V ON slice output. Usually connected to A VDD .
Input control pin for V ON slice output.
