LM2734 Thin SOT 1A Load Step-Down DC-DC Regulator

Check for Samples: LM2734

FEATURES

DESCRIPTION

The LM2734 regulator is a monolithic, high frequency,

PWM step-down DC/DC converter in a 6-pin Thin

SOT package. It provides all the active functions to

provide local DC/DC conversion with fast transient

response and accurate regulation in the smallest

possible PCB area.

Switching Frequencies

With a minimum of external components and online

design support through WEBENCH^®, the LM2734 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 3V to 20V input operating range down to the

minimum output voltage of 0.8V. Switching frequency

is internally set to 550kHz (LM2734Y) or 1.6MHz

(LM2734X), allowing the use of extremely small

surface mount inductors and chip capacitors. Even

though the operating frequencies are very high,

efficiencies up to 90% are easy to achieve. External

shutdown is included, featuring an ultra-low stand-by

current of 30nA. The LM2734 utilizes current-mode

control and internal compensation to provide high-
