TPS62806-7-8EVM083 Evaluation Module

The TPS62806-7-8EVM083 (BSR083-001) facilitates the evaluation of the TPS6280x family of 600-mA,
step-down converters with 2.3-µA I

Q

in tiny 1.05-mm by 0.7-mm WCSP packages with 0.35-mm pitch. The

EVM contains 3 separate circuits to create output voltages between 0.4 V and 3.3 V from higher input
voltages between 1.8 V and 5.5 V. All circuits have a maximum height of 1 mm. The TPS6280x is a highly
efficient and tiny solution for point-of-load (POL) converters for space-constrained applications, such as
wearables and smart phones.
