Frequently Asked Questions

What is the input voltage range and maximum output current of the LTC1877EMS8#TR?

The LTC1877EMS8#TR accepts input voltages from 2.65 V to 10 V and delivers a regulated output from 0.8 V to 10 V at up to 0.6 A continuous output current. This range covers single-cell Li-ion (2.7 V to 4.2 V) through 5 V and 9 V system rails, making it versatile for portable and embedded power supply designs.

How does synchronous rectification in the LTC1877EMS8#TR improve efficiency compared to non-synchronous step-down converters?

The LTC1877EMS8#TR uses an internal synchronous MOSFET to replace the external Schottky diode used in non-synchronous converters, reducing conduction losses by replacing a typical 0.3 V to 0.5 V diode forward voltage drop with a low-resistance FET switch. This can improve efficiency by 5% to 10% at 0.6 A load, extending battery runtime in handheld and wearable devices.

For a 3.3 V to 1.8 V regulation on a compact IoT sensor board, how suitable is the LTC1877EMS8#TR?

The LTC1877EMS8#TR is well-suited for this application: with a 3.3 V input within its 2.65 V to 10 V range and an output set to 1.8 V within its 0.8 V to 10 V adjustable range, it delivers up to 0.6 A in a tiny 8-pin MSOP footprint (approximately 3 mm x 3 mm), making it ideal for compact IoT sensor boards needing an efficient LDO replacement.

What switching frequency does the LTC1877EMS8#TR operate at, and how does it affect external component selection?

The LTC1877EMS8#TR operates at a fixed internal switching frequency of approximately 550 kHz, which allows the use of small surface-mount inductors in the 4.7 µH to 10 µH range and low-profile ceramic output capacitors of 10 µF to 22 µF, reducing the total solution size to under 20 mm² on a typical PCB layout.
