Frequently Asked Questions
What input voltage range does the TPS629203DRLR support, and which power sources is it compatible with?
The TPS629203DRLR accepts an input voltage from 3 V to 17 V with a nominal of 12 V. This wide range makes it compatible with single-cell or multi-cell lithium batteries, 12 V automotive supplies, and 5 V USB sources, giving designers flexibility across portable, industrial, and automotive applications without changing the power IC.
How does the PFM mode of the TPS629203DRLR improve efficiency in light-load IoT applications?
At light loads, the TPS629203DRLR automatically transitions from PWM to pulse-frequency modulation (PFM), reducing switching losses and quiescent current to extend battery runtime. In sleep or standby modes where load currents drop below a few milliamps, PFM can improve efficiency by more than 10 percentage points compared to fixed-frequency PWM operation alone.
What footprint does the TPS629203DRLR use, and what are the advantages for high-density PCB layouts?
The TPS629203DRLR uses an 8-pin SOT flat-lead (DRL) package, which has a very small PCB footprint of approximately 2 mm × 2 mm. This compact form factor allows placement alongside other power-management devices in dense layouts typical of wearable and IoT module designs where board area is limited to under 10 cm².
