Note 1: The SOIC package used is thermally enhanced through the use of a fused integral leadframe. The power rating is based on a printed
circuit board heat spreading capability equivalent to 2 square inches of copper connected to the GND pins. Typical multi-layer boards
using power plane construction will provide this heat spreading ability without the need for additional dedicated copper area. (Please
consult with factory for thermal evaluation assistance.)
Note 2: The hysteresis defines the maximum level of acceptable disturbance on V
CC during switching. It is recommended that the VCC source
impedance be kept below 0.25
Ω to ensure the switching disturbance remains below the hysteresis during select/deselect transitions.
An input capacitor may be required to help minimize the switching transient.
Note 3: Ground pin current consists of controller current (0.15mA) and regulator current if enabled. The controller always draws 0.15mA from
either V
CC or VOUT , whichever is greater. All regulator current is supplied exclusively from VCC . At high load currents a small increase
occurs due to current limit protection circuitry.
