DESCRIPTION
INPUT (L) Logic input, ACTIVE LOW. Setting SLEEP to low puts the TPS4100A in sleep
mode. Input range is 0 to 5V with 3.3V compliant inputs.
INPUT (L) Non-inverted switching modulator inputs.
INPUT (L) Inverted switching modulator inputs.
INPUT (L) Logic Input, ACTIVE LOW. Setting MUTE to low puts the device in mute mode.
Typically driven by external power supply or microcontroller. Input range is 0 to
5V with 3.3V compliant inputs.
INPUT (L) Logic input, ACTIVE HIGH. Enables Analog Mode operation. Typically driven
by Tripath controller. Input range is 0 to 5V with 3.3V compliant inputs.
