Key Features
- Current-mode PWM control with programmable switching frequency up to 1 MHz for minimal external components
- Wide input voltage range of 2.65 V to 5.5 V supports single-cell Li-Ion and USB power rails
- SOT-23-6 package with peak switch current up to 1 A enables compact high-efficiency boost designs
Applications
TLV61048DBVR is well suited for battery-powered portable devices such as wearables and IoT nodes that need to boost a single Li-Ion cell (3.7 V) to a regulated 5 V rail. Its wide 2.65 V to 5.5 V input range also makes it ideal for USB-powered applications requiring a higher output voltage. The 1 MHz switching frequency keeps inductors and capacitors small, reducing BOM cost and board space.

Frequently Asked Questions
What is the input voltage range supported by TLV61048DBVR, and which battery chemistries does it accommodate?
TLV61048DBVR operates from a 2.65 V to 5.5 V input, covering single-cell Li-Ion (nominal 3.7 V), alkaline, and NiMH battery stacks, making it ideal for portable and wearable designs requiring flexible power sourcing.
How high can TLV61048DBVR switch its internal FET, and why does that matter for output power?
The integrated switch supports a peak current up to 1 A, which allows the boost converter to deliver meaningful output power even at lower duty cycles; at 3.3 V input boosting to 5 V the device can sustain tens of milliamps of continuous output current efficiently.
What switching frequency does TLV61048DBVR use, and how does that affect passive component selection?
TLV61048DBVR can operate at up to 1 MHz switching frequency, enabling the use of small-footprint inductors in the 2.2 µH to 10 µH range and ceramic capacitors under 10 µF, significantly reducing the total PCB area required for the power stage.
In which package does TLV61048DBVR ship, and how does it help in space-constrained designs?
The part ships in the SOT-23-6 package, a 6-pin small-outline package measuring roughly 2.9 mm × 1.6 mm, which is well within the footprint budget for compact IoT and wearable boards where every square millimeter matters.
When would an engineer choose TLV61048DBVR over a charge-pump solution for generating 5 V from a Li-Ion cell?
A PWM boost like TLV61048DBVR is preferred over a charge pump when load currents exceed roughly 50 mA, because the inductor-based topology achieves higher efficiency (typically above 85%) at those currents, whereas unregulated charge pumps lose efficiency and regulation accuracy above their rated output current.
