Frequently Asked Questions
How many output power rails can the TPS659109A1RSLR manage simultaneously?
The TPS659109A1RSLR integrates 12 independent output channels in a single PMIC, allowing it to supply 12 separate voltage rails simultaneously. This eliminates the need for multiple discrete regulators and simplifies power sequencing for complex SoC platforms such as application processors used in tablets, industrial HMIs, and embedded Linux systems.
What input voltage sources are compatible with the TPS659109A1RSLR?
The device accepts input voltages from 1.7 V to 5.5 V, covering single-cell Li-ion batteries (nominally 3.7 V), USB 5 V bus power, and regulated 3.3 V adapter rails. This flexibility makes it suitable for designs that need to operate across a range of power source scenarios without requiring additional pre-regulation stages.
Why is the QFN-48 package a good choice for the TPS659109A1RSLR in power management designs?
The 48-pin QFN (Quad Flat No-Lead) package offers a small PCB footprint with an exposed thermal pad on the underside, enabling efficient heat dissipation when the PMIC is supplying 12 output rails. This combination of compact size and good thermal performance is advantageous in mobile and industrial designs where board area and operating temperature are both constrained.
Does the TPS659109A1RSLR support adjustable voltage thresholds for power sequencing?
Yes, the TPS659109A1RSLR features adjustable threshold capability, allowing designers to configure the turn-on and turn-off voltage levels for individual output rails. Proper power sequencing across 12 channels is essential for SoC startup reliability, preventing latch-up and ensuring correct initialization of processor core, DDR memory, and I/O power domains in the correct order.
