Frequently Asked Questions
What output voltage range can TPS62351DRCR regulate to and which processor core rails does it support?
TPS62351DRCR adjusts its output from 0.9 V to 1.6875 V, covering the core voltage rails of ARM Cortex-M and Cortex-A processors, FPGAs, and memory interfaces that commonly demand 1.0 V, 1.2 V, or 1.5 V. The 0.9 V floor also supports next-generation sub-1 V core designs, making TPS62351DRCR a future-proof choice for low-voltage digital loads.
How does the PFM mode of TPS62351DRCR extend battery life in low-power wireless sensor designs?
At light loads below roughly 30 mA, TPS62351DRCR automatically transitions from PWM to pulse-frequency modulation (PFM), reducing switching losses and achieving efficiencies above 80% even at 1 mA output current. This mode saves several milliwatts of quiescent power in a sensor node sleeping between 100 ms data transmissions, extending coin-cell battery life by 20% or more compared to a fixed-PWM regulator.
Which input supply scenarios are compatible with TPS62351DRCR in a Li-ion-powered portable design?
TPS62351DRCR operates from 2.7 V to 5.5 V input, covering the full discharge range of a single-cell Li-ion battery from 4.2 V charged down to 2.7 V depleted, as well as 5 V USB bus power. This eliminates the need for a separate LDO pre-regulator and allows the device to maintain regulation across the entire usable battery capacity.
For a compact multi-rail PMU board, how does TPS62351DRCR's 10-pin VSON package compare to larger-footprint alternatives?
The 10-pin VSON (S-PDSO-N10) package measures approximately 3 mm × 3 mm, roughly half the board area of an equivalent SOT-23-5 or MSOP-8 solution, enabling tighter placement of multiple point-of-load rails on a densely populated processor board. Its exposed pad also improves thermal performance, keeping junction temperature at least 10°C lower than a no-pad package at 500 mA output.
