Key Features
- Synchronous boost converter with 3.6 A switch current and 16 V output capability delivers high efficiency up to 95% for single-cell Li-Ion to multi-rail power trees
- Integrated load disconnect switch prevents reverse leakage current from output to input when the device is disabled, extending battery run time in portable designs
- BGA package minimizes PCB footprint versus comparable SOT or QFN solutions, enabling ultra-compact layout for wearables and miniature IoT nodes
Applications
The XTPS61372YKBR is designed for single-cell Li-Ion powered portable devices that require a boosted 5 V to 16 V rail for displays, RF front-ends, or white-LED backlighting, delivering up to 3.6 A switch current with synchronous rectification for peak efficiency above 90%. Its integrated load disconnect is particularly valuable in smartphone accessories and TWS earbuds where output rail leakage during standby must be below 1 µA to meet multi-day battery life targets. Industrial handheld instruments and wireless sensor nodes benefit from the combination of high output voltage and compact BGA footprint for high-density power supply designs.

Frequently Asked Questions
What peak output voltage can XTPS61372YKBR produce from a single Li-Ion cell input?
The XTPS61372YKBR boosts up to 16 V output from a 2.7 V to 5.5 V input range, allowing a single Li-Ion cell (3.0 V–4.2 V) to supply high-voltage rails for AMOLED displays, RF power amplifiers, or motor driver ICs. The 3.6 A internal switch current sustains the boost conversion at output currents up to several hundred milliamperes depending on the input-output voltage ratio.
How does the integrated load disconnect feature reduce standby power in battery-powered devices?
The load disconnect switch opens the output path when the device is in shutdown mode, reducing reverse leakage from output capacitors back to the battery to below 1 µA. In a 500 mAh Li-Po cell this extends standby time by several days compared to a boost without disconnect, which can leak 10–100 µA through the body diode of an unswitched inductor-FET path.
For a TWS earbud design, why might XTPS61372YKBR be selected over a linear boost approach?
The XTPS61372YKBR achieves up to 95% conversion efficiency versus 50–60% for a linear boost at high step-up ratios, directly reducing heat dissipation inside the tight thermal envelope of a 10 mm × 6 mm earbud housing. Its BGA package has a sub-4 mm² land area, fitting alongside a codec and Bluetooth SoC in the dense PCB stack found in premium TWS products.
What input voltage range does XTPS61372YKBR support, and can it start up from a deeply discharged 3.0 V Li-Ion cell?
The input voltage range is 2.7 V to 5.5 V, which covers a Li-Ion cell from its minimum cutoff voltage of approximately 3.0 V to a fully charged 4.2 V. The device can start up from 2.7 V, allowing operation even when a partially discharged cell drops below the nominal 3.7 V, ensuring uninterrupted power to connected subsystems during the final stages of battery discharge.
