Overview
The LM2736YMK/NOPB is a high-performance, monolithic PWM step-down DC/DC converter produced by Texas Instruments. This regulator is housed in a 6-pin Thin SOT package, making it ideal for applications where space is limited. It provides all the active functions necessary for local DC/DC conversion, offering fast transient response and accurate regulation. The LM2736YMK/NOPB is designed to operate over a wide input voltage range of 3.0 V to 18 V and can deliver an output current of up to 750 mA. With its high switching frequencies and internal compensation, this regulator is simple to use and requires a minimum of external components.
