Frequently Asked Questions
What input voltage range does the LTC3531ES6-3#TRMPBF support for buck-boost operation?
The LTC3531ES6-3#TRMPBF supports an input voltage range of 1.8 V to 5.5 V, enabling seamless buck-boost operation from single-cell lithium-ion batteries throughout their full discharge cycle. The nominal input is 3.6 V, and the fixed 3 V output remains regulated across the entire input range with up to 200 mA load current.
How does the LTC3531ES6-3#TRMPBF's synchronous topology benefit battery-powered IoT sensor designs?
The synchronous buck-boost topology of the LTC3531ES6-3#TRMPBF eliminates external catch diodes and reduces conduction losses, extending battery life in IoT sensor nodes drawing up to 200 mA from 1.8 V minimum input. Voltage-mode PWM control ensures low output ripple, which is beneficial for ADC references and RF front-end circuits operating at 3 V.
For a compact wearable PCB, how does the SOT-23-6 package of the LTC3531ES6-3#TRMPBF compare in board space to larger regulators?
The SOT-23-6 package of the LTC3531ES6-3#TRMPBF occupies approximately 8 mm² footprint, significantly smaller than SO-8 or MSOP-8 packages used by competing 200 mA regulators. This compact 6-pin layout with minimal external passives makes the LTC3531ES6-3 well-suited for wearables and small-form-factor IoT designs where board area is limited to a few square centimeters.
