PHASE1
Logic level input: phase switching
When PHASE1 = high: Output pin states: OUTA: high, OUTA-: low.
When PHASE1 = low: Output pin states: OUTA: low, OUTA-: high.
15
ST
Standby mode setting
When ST = high: the IC operates in normal operating mode.
When ST = low: the IC operates in standby mode. The V

1VREG
1 V regulator circuit output
The LB11948 includes an internal 1 V regulator circuit, and this pin is the output from that circuit. The VREF1 and VREF2
reference voltages can be set by voltage dividing the 1 V regulator output.

PHASE2
Logic level input: phase switching
When PHASE2 = high: Output pin states: OUTA: high, OUTA-: low.
When PHASE2 = low: Output pin states: OUTA: low, OUTA-: high.
