Key Features
- Dual switching frequency selection of 650 kHz or 1.2 MHz enables trade-off between efficiency and compact filter size
- Forced PWM mode maintains low output ripple at light loads for noise-sensitive analog and RF applications
- Wide input range 2.3V to 6V with 2A peak switch current supports single-cell Li-ion to multi-cell battery systems
Applications
The TPS61085DGKR is ideal for portable electronics requiring boosted supply rails such as LCD bias, white LED drivers, and AMOLED display power supplies. It is widely used in handheld instruments, industrial sensors, and IoT devices where a single-cell or multi-cell battery must be stepped up to power 5V to 18.5V loads. The forced PWM mode makes it particularly valuable in RF and audio applications where switching noise must remain constant and predictable.

Frequently Asked Questions
What is the input voltage range and output voltage range of the TPS61085DGKR?
The TPS61085DGKR accepts an input voltage from 2.3V to 6V and can produce an adjustable output voltage from 2.8V to 18.5V, making it suitable for boosting single-cell Li-ion (3.7V nominal) or two-cell AA/AAA battery stacks to higher system voltages.
What switching frequencies does the TPS61085DGKR support?
The TPS61085DGKR supports two selectable switching frequencies: 650 kHz for higher efficiency and 1.2 MHz for reduced inductor and capacitor size. The frequency is set by a resistor on the RT pin, allowing designers to optimize for PCB area or power efficiency.
What is the package type and pin count of the TPS61085DGKR?
The TPS61085DGKR comes in an S-PDSO-G8 package (MSOP-8), an 8-pin small outline surface-mount package with a thermal pad. The compact footprint is suitable for space-constrained portable and wearable device designs.
When should forced PWM mode be used with the TPS61085DGKR?
Forced PWM mode should be selected when constant switching frequency is critical, such as in RF systems, audio equipment, and precision analog circuits where variable frequency PFM switching would introduce unpredictable noise. In forced PWM mode, the TPS61085DGKR maintains fixed frequency operation even at light loads, trading some light-load efficiency for noise predictability.
