Two-Phase Interleaved Operation
Operates With Pre-Biased Outputs
1-V to 40-V Power Stage Operation Range
Requires VIN5 @ 50 mA (typ) Depending on
External MOSFETs and Switching
Frequency
10-μA Shutdown Current
Programmable Switching Frequency up to 1
MHz/Phase
Current Mode Control with Forced Current
Sharing
Better than 1% Internal 0.7-V Reference
Resistive Divider Sets Direct Output Over
Voltage Threshold.
Programmable Input Undervoltage Lockout
True Remote Sensing Differential Amplifier
Resistive or Inductor’s DCR Current Sensing
32-Pin QFN Package
Can Be Used with TPS40120 to Provide a 6-Bit
The TPS40131 is a two-phase synchronous buck
Digitally Controlled Output
controller that is optimized for low-output voltage,
high-output current applications powered from a
supply between 1 V and 40 V. A multi-phase
converter offers several advantages over a single
Point-of-Load Converter
power stage including lower current ripple on the

to load steps, improved power handling capabilities,
and higher system efficiency.

frequency up to 1 MHz, resulting in an effective
ripple frequency of up to 2 MHz at the input and the
output. The two phases operates 180 degrees
out-of-phase.
