32-Pin QFN Package
The TPS40132 is a two-phase synchronous buck
Can Be Used with TPS40120 to Provide a 6-Bit
controller that is optimized for low-output voltage,
Digitally Controlled Output
high-output current applications powered from a
supply between 1 V and 40 V. A multi-phase
converter offers several advantages over a single
power stage including lower current ripple on the

and higher system efficiency.
Networking Equipment
Each phase can be operated at a switching frequency
Telecommunications Equipment
up to 1 MHz, resulting in an effective ripple frequency
