Applications
The TLV62568 is used in portable consumer electronics — such as fitness trackers, wireless earbuds, and compact IoT sensor nodes — where a 5 V USB or single-cell Li-ion rail must be stepped down to 1.8 V or 3.3 V with minimal board footprint. Its 1 A current rating also suits low-power industrial microcontroller supply rails in space-constrained embedded designs. Battery-powered BLE and Wi-Fi modules running from 3.7 V cells rely on its 2.5 V minimum input to maintain regulation near end-of-discharge.

Frequently Asked Questions
Can the TLV62568DRLR operate directly from a single-cell Li-ion battery throughout its full discharge range?
Yes. The TLV62568 accepts input voltages as low as 2.5 V, which covers a Li-ion cell from its 4.2 V full charge down to approximately 2.7 V near end of discharge. This enables the converter to sustain a regulated 1.8 V or 3.3 V output rail without dropping out before the battery management circuit cuts off the cell.
How much output current can the TLV62568DRLR supply, and is that sufficient for a BLE SoC plus peripherals?
The device supports 1 A continuous output current with synchronous rectification. A typical BLE SoC draws 5 mA to 20 mA in active radio mode, and connected sensors and an MCU may add another 50 mA to 100 mA. The 1 A rating provides ample headroom for a complete wireless sensor node without needing a higher-current converter.
Why choose voltage-mode PWM control for the TLV62568 rather than a hysteretic or COT converter?
Voltage-mode PWM operates at a fixed switching frequency, which simplifies EMI filter design and avoids the variable-frequency noise spectrum of hysteretic regulators. For consumer electronics and IoT products that must pass FCC or CE radiated emissions tests, the predictable 2.5 V to 5.5 V input, fixed-frequency operation of the TLV62568 reduces the EMI burden on the PCB layout and input filter.
Does the SOT-23 package of the TLV62568DRLR allow hand-soldering during prototyping?
The 6-pin SOT-23 package has 0.95 mm pitch leads exposed on the package perimeter, making hand-soldering feasible with a fine-tip iron during prototyping. For production, the small footprint is fully compatible with automated SMT assembly lines, and the SOT563 variant of the same device offers an even smaller 6-pin body for volume manufacturing.
For a 5 V USB-powered accessory stepping down to 3.3 V at 500 mA, is the TLV62568 a better fit than a 500 mA LDO?
The TLV62568 is significantly more efficient in this case. A linear regulator dissipates (5 V − 3.3 V) × 0.5 A = 0.85 W as heat, requiring a larger package or heatsink. The synchronous buck converter achieves over 90% efficiency at those conditions, dissipating less than 0.17 W — a 5× reduction in thermal load that allows the 6-pin SOT-23 to run cool without a heat spreader.
