TPS628436-7-8EVM-167 Evaluation Module
The TPS628436-7-8EVM-167 (BSR167) facilitates the evaluation of the TPS62843 family of 600-mA, step-down
converters with 300-nA I
Q
separate circuits to create output voltages between 0.4 V and 3.6 V from higher input voltages between 1.8 V
and 5.5 V. All circuits have a maximum height of 1.0-mm. The TPS62843x is a highly efficient and tiny solution
for point-of-load (POL) converters for space-constrained applications, such as wearables and smartphones.
