Frequently Asked Questions
What is the input voltage range of the LM2736YMK/NOPB?
The LM2736YMK/NOPB accepts an input voltage from 3V to 18V, with a nominal operating point of 5V. This wide input range makes it compatible with a variety of power sources including Li-ion batteries, USB rails, and regulated 12V or 15V supplies commonly found in industrial and consumer designs.
What output current can the LM2736YMK/NOPB deliver?
The LM2736YMK/NOPB is rated for a maximum continuous output current of 0.75A. It uses current-mode pulse width modulation (PWM) control, which provides excellent load transient response and inherent cycle-by-cycle overcurrent limiting for robust operation across varying load conditions.
What package does the LM2736YMK/NOPB come in, and is it lead-free?
The LM2736YMK/NOPB is supplied in a 6-pin SOT23 package (JESD-30 code R-PDSO-G6). It is fully RoHS-compliant and lead-free (Pb-free code: Yes, JESD-609 code: e3), making it suitable for designs that must meet modern environmental regulations such as those required in European and Asian markets.
Where can I use the LM2736YMK/NOPB in my design?
This step-down converter is ideal for portable consumer electronics, IoT devices, wearables, and industrial sensor modules. Its light load efficiency feature is particularly valuable in battery-powered applications where the system frequently operates at low current draw, helping to extend battery life significantly compared to standard PWM regulators.
