Key Features
- Integrated inductor in an ultra-compact 2 mm × 2.5 mm × 1.1 mm SIP package reduces total solution footprint by up to 60% versus discrete buck regulators
- 2 A continuous output current from a 2.4 V to 5.5 V input range covers standard 3.3 V and 5 V rail step-down requirements
- PWM current/voltage-mode control with adjustable output voltage enables precise regulation for noise-sensitive loads in space-constrained designs
Applications
TPSM828222SILR targets wearable electronics, IoT sensor nodes, and portable medical devices where a 2 A regulated rail must fit within a footprint smaller than 5 mm². It is used in FPGA and DSP core voltage supplies on compact SoM boards that cannot accommodate discrete inductors. The module also serves solid-state drive power planes and small-form-factor industrial controllers that need a 2.4 V to 5.5 V input buck converter with minimal external components.

Frequently Asked Questions
How does the integrated inductor in TPSM828222SILR reduce BOM complexity compared to a discrete 2 A buck regulator?
TPSM828222SILR integrates the power inductor inside the 2 mm × 2.5 mm × 1.1 mm SIP module, eliminating the need for an external inductor rated at 2 A or higher. A discrete solution typically requires a separate 1 µH to 4.7 µH inductor occupying at least 4 mm² of PCB area plus routing keep-outs, while the module requires only input and output capacitors, reducing the component count by 3 to 5 parts.
Which output voltage range can TPSM828222SILR regulate from a 3.3 V input rail, and how is it set?
From a 3.3 V input, TPSM828222SILR can regulate outputs down to approximately 0.6 V using a feedback resistor divider on the FB pin. The output voltage is programmable by selecting two resistors, typically in the 10 kΩ to 100 kΩ range, allowing voltage steps as fine as 50 mV. Maximum output current remains 2 A across the 2.4 V to 5.5 V input range, constrained only by the input-to-output differential.
For a compact IoT PCB, how does TPSM828222SILR's SIP-10 footprint compare to a standard QFN-based buck regulator plus inductor?
TPSM828222SILR occupies a total solution area of approximately 5 mm² (2 mm × 2.5 mm), whereas a typical QFN-10 buck controller plus a 2 mm × 2 mm inductor plus input and output capacitors requires 25 mm² to 35 mm². The 1.1 mm maximum height also fits under shielding cans as thin as 1.5 mm, a critical advantage for wearables and hearing-aid-class devices with less than 2 mm vertical clearance.
