3 Description
The TPS65290 device is a power-managemant
integrated circuit (PMIC) designed to operate in
applications dependent on efficient power
management over a wide range of system load
conditions ranging from fractions of a microamp to a
few hundred milliamps. The device operates over a
wide 2.2-V to 5-V input-voltage range and
incorporates a very low-quiescent-current always-on
power supply, a 500-mA buck-and-boost converter, a
150-mA low-dropout regulator (LDO) and eight
power-distribution switches. The always-on supply
features three different factory selectable options:
30‑mA buck converter with 300-nA quiescent current,
10‑mA LDO with 400-nA quiescent current, and
10‑mA zero IDDQ drop with 100-nA quiescent
current. The buck-boost converter employs PFM or
PWM operation with forced PWM option, for
maximum overall efficiency. A designer can use the
switches to support different configurations for the
various loads supported by the TPS65290 device. For
energy-harvesting applications, the device integrates
a programmable input-voltage monitor to allow for
connection and disconnection of the different power
blocks and switches without the intervention of the
master processor.
