The TPS62840-1YBGEVM56 (BSR056-001) facilitates the evaluation of the TPS6284xYBG family of 750-
mA, step-down converters with 60-nA I
The EVM contains 2 separate circuits to create output voltages between 0.8 V and 3.3 V from higher input
voltages between 1.8 V and 6.5 V. All circuits have a maximum height of 1 mm. Due to its extremely low
I
, the TPS6284x provides a long battery lifetime for systems which have very low current consumption
Q
states such as wearables, Internet of Things- (IoT-) connected devices, and other portable end equipment.
