LM2734ZSDX

Voltage Regulators - DC DC Switching Regulators Overview

The LM2734ZSDX is a discontinued synchronous step-down DC-DC regulator manufactured by Texas Instruments. It operates with an input voltage range of 3V to 20V and provides a single adjustable output from 0.8V to 18V at up to 1A. The device features a fixed 3MHz switching frequency, enabling the use of small external components. It is housed in a compact 6-WSON package measuring 3mm x 3mm with an exposed thermal pad for efficient heat dissipation. The component supports operation across a junction temperature range of -40°C to 125°C.
