Applications
The TPS65020ARHAR is designed for portable consumer electronics and embedded Linux platforms such as handheld industrial terminals, wireless sensor nodes, and single-board computers powered by a single-cell Li-Ion battery. Its I2C interface and dynamic voltage scaling allow the host processor to adjust core voltage in real time, saving power during low-activity states. The six regulated outputs replace multiple discrete regulators, shrinking BOM size and simplifying power sequencing across DRAM, core, and I/O voltage domains.

Frequently Asked Questions
How many regulated output rails does the TPS65020ARHAR provide, and what current can each DC/DC supply?
The device provides 6 regulated rails: 3 synchronous step-down DC/DC converters and 3 LDOs. Each DC/DC converter is rated up to 1.5 A continuous output current, making the total available current 4.5 A across the switching rails—sufficient to power a dual-core application processor, LPDDR2 memory, and peripheral I/O from a single PMIC.
What input voltage range does the TPS65020ARHAR accept, and is it compatible with a single-cell Li-Ion battery?
The device accepts input voltages from 2.7 V to 5.5 V, which covers the entire discharge curve of a single-cell Li-Ion battery (4.2 V full to 3.0 V cutoff). No boost pre-regulator is needed, and the integrated under-voltage lockout protects the load circuits from brownout during deep battery discharge below 2.7 V.
How does the I2C dynamic voltage scaling feature of the TPS65020ARHAR benefit a battery-powered processor system?
Dynamic voltage scaling via I2C allows the host SoC to step the core voltage down by 25 mV to 100 mV increments during idle or low-frequency states. For example, reducing the CPU core from 1.2 V to 1.0 V at 400 MHz can cut dynamic power by up to 30%, extending battery life by 20% or more in a typical portable application with 2000 mAh capacity.
How does using the TPS65020ARHAR compare to discrete regulators in a compact portable device design?
Replacing six discrete regulators with the TPS65020ARHAR reduces component count by approximately 20–30 passives and eliminates multiple inductor footprints, shrinking total power-stage area from over 200 mm² to roughly 50 mm². The integrated power sequencing and soft-start also remove the need for a separate sequencing IC, further simplifying layout and reducing BOM cost.
