The KTB851EVD-ADJ-TR is a Buck (step-down) DC-DC converter from Kinetic Technologies, optimized for battery-powered portable electronics. It accepts inputs from 2.7V to 5.5V and provides an adjustable output from 0.6V to 5.5V, supporting up to 600mA of load current. The 1.6MHz switching frequency enables the use of miniature external components, making it perfect for compact designs. The 6-UFDFN package with exposed pad aids in thermal dissipation, ensuring reliable operation in enclosed devices.
- Ultra-Compact Solution: 1.6MHz switching allows for 0.47µH inductors and 0402 capacitors, reducing PCB area by up to 50%.
- Low Quiescent Current: Extends standby time in battery-operated devices, critical for IoT and wearables.
- 600mA Peak Current: Handles short bursts from wireless transmitters without voltage droop.
- Adjustable Output from 0.6V: Supports the latest low-voltage processors and memory.
Bluetooth Audio Earbuds
The KTB851EVD-ADJ-TR efficiently steps down from a 3.7V Li-ion battery to 1.8V for the audio codec and 3.3V for the Bluetooth controller. The 1.6MHz frequency allows for a tiny solution size inside the earbud housing.
Smartwatches & Fitness Bands
With a 2.7V-5.5V input range, this converter handles both single-cell Li-ion and USB 5V inputs. The 600mA output powers the display, haptic driver, and heart-rate sensor simultaneously.
Wireless Keyboards & Mice
For peripherals powered by 2xAA batteries (2.4V-3.2V), the KTB851EVD-ADJ-TR provides a stable 3.0V rail for the RF transceiver and MCU, ensuring consistent performance as batteries discharge.
Portable Medical Monitors
Glucose meters and pulse oximeters require precise low-noise power. This buck converter delivers clean 1.8V or 3.3V rails from a coin cell or small Li-ion battery, maintaining accuracy.
Smart Tags & Trackers
Bluetooth trackers need efficient power conversion to maximize battery life. The KTB851EVD-ADJ-TR's high efficiency at low currents ensures months of operation from a CR2032 battery.
