The TPS62913-IBB-EVM (BSR161A) evaluation module (EVM) facilitates the evaluation of the TPS62912 2-A and TPS62913 3-A pin-to-pin compatible low-noise (< 20 μVRMS) and low ripple (< 10 μVRMS) buck converters in small 2-mm by 2-mm QFN packages when used in an inverting buck-boost (IBB) topology. The TPS62913-IBB-EVM uses the 3-A TPS62913 to output a -5-V output voltage from input voltages between 3 V and 11.5 V. Due to its extremely low noise, the TPS6291x is a high-efficiency alternative to low-dropout (LDO) linear regulators in noise-sensitive circuits that need a negative output voltage such as optical modules for telecom infrastructure, instrumentation and operational amplifiers for medical, test and measurement, and aerospace and defense applications.
