NAME/FUNCTION TYPE

DESCRIPTION

1

SLEEPB

INPUT (L) Logic input, ACTIVE LOW. Setting SLEEP to low puts the TPS4100 in sleep

mode. Input range is 0 to 5V with 3.3V compliant inputs.

2, 4, 6, 8

Y1, Y2, Y3, Y4

INPUT (L) Non-inverted switching modulator inputs.

3, 5, 7, 9

Y1B, Y2B, Y3B, Y4B

INPUT (L) Inverted switching modulator inputs.

10

MUTEB

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.

11

AM

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.

12

5VGEN

OUTPUT

On chip 5V regulator bypass capacitor connection
