Frequently Asked Questions
What input voltage range does the RWY0009A support for battery-powered designs?
The RWY0009A operates from a 2.75 V to 6 V input range, making it directly compatible with single-cell Li-ion batteries (nominal 3.6 V to 4.2 V) and two-cell alkaline or NiMH packs. This broad range ensures continuous regulation even as a battery discharges toward its minimum cutoff voltage.
How does the adjustable switching frequency of the RWY0009A benefit system-level EMI management?
By allowing the designer to tune the switching frequency, the RWY0009A enables interference to be spread away from sensitive RF bands or fixed to a frequency that pairs efficiently with the chosen output inductor. Typical adjustable-frequency converters in this class support frequency selection across a range such as 300 kHz to 3 MHz, reducing LC filter size while meeting conducted emissions targets.
In which compact power supply scenarios is the RWY0009A a better choice than a fixed-frequency LDO regulator?
When the input-to-output voltage differential exceeds 0.5 V and load currents exceed a few tens of milliamps, a switching step-down converter like the RWY0009A delivers significantly higher efficiency than an LDO, which dissipates excess voltage as heat. For a 4.2 V input regulated to 1.8 V at 200 mA, efficiency gains of 20 percentage points or more are typical, extending battery life in portable designs.
