Product Overview

The LM2734ZMK/NOPB is a monolithic high-frequency PWM step-down DC-to-DC Converter provides all the active functions to provide local DC-to-DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components and online design support through WEBENCH™, the LM2734Z is easy to use. The ability to drive 1A loads with an internal 300mΩ NMOS switch using state-of-the-art 0.5µm BiCMOS technology results in the best power density available. The world class control circuitry allows for ON-times as low as 13ns, thus supporting exceptionally high-frequency conversion over the entire 3 to 20V input operating range down to the minimum output voltage of 0.8V. Switching frequency is internally set to 3MHz, allowing the use of extremely small surface mount inductors and chip capacitors. Even though the operating frequency is very high, efficiencies up to 85% are easy to achieve.
