Key Features
- Built-in inductor in a 10-pin DMA module package reduces total solution footprint to under 15 mm² for 1 A step-down rails
- 2.4 V to 5.5 V input range covers USB, single-cell Li-Ion, and regulated 5 V supply rails with a single module
- Current/voltage-mode PWM control provides stable transient response and accurate output regulation across 0 A to 1 A load steps
Applications
The TPSM828212SILR is designed for IoT gateways, industrial sensor nodes, and wearable electronics where board space is at a premium and inductor selection adds engineering overhead. Its integrated inductor eliminates external magnetic component selection, allowing engineers to complete a point-of-load regulator design with fewer than 5 external passives. The 2.4 V to 5.5 V input range makes it directly compatible with USB-powered and single-cell Li-Ion battery applications.

Frequently Asked Questions
How does the integrated inductor in TPSM828212SILR reduce design effort compared to a discrete buck converter solution?
By integrating the inductor inside the 10-pin DMA module, the TPSM828212SILR eliminates the need for an external inductor selection, including saturation current rating, DCR matching, and shielding considerations. A discrete alternative typically requires specifying a 1 µH to 2.2 µH inductor rated for at least 1.5 A saturation current; the module approach replaces that component and its footprint with a single pre-tested assembly, saving 2–3 hours of magnetics engineering per design.
Can TPSM828212SILR power a 3.3 V rail directly from a USB 5 V bus at 1 A load?
Yes. The TPSM828212SILR accepts up to 5.5 V input, so it operates directly from a USB 5 V bus. At 1 A output current and 3.3 V output voltage, the module delivers 3.3 W of regulated output power with a typical PWM efficiency above 85%, dissipating less than 580 mW as heat — well within the module's thermal rating for standard PCB applications.
What is the minimum input voltage for TPSM828212SILR, and can it regulate from a nearly-depleted single-cell Li-Ion battery?
The TPSM828212SILR starts up and regulates with input voltages as low as 2.4 V, which is below the typical 2.7 V cutoff voltage of most Li-Ion protection circuits. This means it continues to regulate through the late discharge phase of a single-cell Li-Ion cell (3.0 V nominal end-of-discharge), extracting maximum energy from the battery before the protection circuit disconnects the load.
For an industrial sensor node with a 5 V power rail, what output voltage range can TPSM828212SILR produce?
The TPSM828212SILR adjustable output can be set anywhere from approximately 0.8 V up to just below the input voltage using a simple 2-resistor feedback divider. From a 5 V input this covers the full range of common digital supply rails: 0.9 V for DDR memory termination, 1.0 V to 1.8 V for FPGA core rails, and 3.3 V for microcontroller I/O, all at up to 1 A continuous output current.
