Key Features

  • 3V to 18V wide input voltage range for versatile power supply compatibility
  • 0.75A output current with current-mode PWM control for fast transient response
  • Optimized light load efficiency reduces power consumption in standby and idle states
  • Compact SOT23-6 package enables high-density PCB designs with minimal board space
  • Internal compensation simplifies design and reduces external component count

Applications

The LM2736YMK/NOPB is well-suited for space-constrained portable and battery-powered applications requiring efficient DC-DC voltage conversion. It is commonly used in handheld consumer electronics, IoT sensor nodes, industrial control modules, and wearable devices where a 3V–18V source must be stepped down to lower supply rails. Its light load efficiency optimization makes it ideal for always-on systems that spend significant time in standby mode.

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.
