What are the key features of TPS628512DRLR?
- 2.7 V to 6 V input range with 2 A output current, covering single-cell Li-ion and 5 V USB rail buck conversion in one design
- Fixed-frequency current-mode PWM control for predictable EMI spectrum and simple loop compensation
- 8-pin SOT583 (SOT-5X3) package with -40°C to 150°C operating range enabling high-temperature industrial and automotive-adjacent designs
What is TPS628512DRLR used for?
The TPS628512DRLR is suited for powering low-voltage MCU and FPGA cores from a 5 V USB or single-cell Li-ion rail in IoT sensors, wearables, and handheld instruments where the SOT583 package minimizes footprint. Its 2 A output current handles processor core rails plus peripheral supply rails simultaneously, reducing the number of regulator ICs on the board. The -40°C to 150°C operating range also makes it appropriate for automotive-adjacent applications such as EV battery management modules and industrial field transmitters.

Frequently Asked Questions
How does TPS628512DRLR's 2.7 V minimum input allow operation through a full Li-ion discharge cycle?
A single-cell Li-ion battery discharges from 4.2 V fully charged to approximately 2.7 V at cutoff, which exactly matches the TPS628512DRLR's 2.7 V minimum input voltage. This allows the regulator to operate continuously across the full battery discharge range without a low-battery early cutoff, maximizing runtime in portable devices by extracting the last milliamp-hours before the protection circuit disconnects the cell.
What output voltage can TPS628512DRLR regulate to when powered by a 5 V USB rail, and at what load current?
From a 5 V USB input, TPS628512DRLR can deliver a fixed regulated output voltage (determined by the specific variant's feedback resistors) at up to 2 A continuous load current, which is sufficient to power a 32-bit MCU core at 1.8 V drawing 500 mA plus 1.5 A of peripheral or sensor load current. The current-mode PWM control maintains regulation within a few millivolts from light load to full 2 A load.
Why is fixed-frequency current-mode PWM in TPS628512DRLR preferable over hysteretic control for EMI-sensitive designs?
Fixed-frequency operation produces a predictable switching spectrum at a single fundamental frequency and its harmonics, making it straightforward to place notch filters or spread-spectrum clocking to meet CISPR 22 Class B EMI limits. In contrast, hysteretic regulators spread switching energy across a frequency range that shifts with load and input voltage, complicating EMI filter design for products destined for FCC or CE certification.
How does the SOT583 package size of TPS628512DRLR benefit a compact IoT sensor board layout?
The SOT583 (8-pin SOT-5X3) package measures approximately 3 mm × 2 mm with a 0.65 mm pitch, occupying roughly 6 mm² of PCB area including the body. Combined with a pair of small external inductors and capacitors totaling about 20 mm², the complete TPS628512DRLR power stage fits in under 30 mm² — a critical advantage for IoT sensor nodes where total board area is constrained to a coin-cell-sized footprint.
