Analog Devices Inc. LT1939EDD is a dual-output power management IC featuring one step-down (buck) and one linear (LDO) regulator. This component supports a wide input voltage range from 3V to 25V. The buck regulator provides an output current of 2A with an adjustable output voltage from 0.8V to 24.25V, operating at switching frequencies between 500kHz and 2.4MHz. The integrated LDO offers an adjustable output voltage also from 0.8V to 24.25V, with a current capability of 1A. The device is housed in a 12-DFN (3x3) surface-mount package, designed for efficient thermal performance with an exposed pad. Operating within a temperature range of -40°C to 125°C, the LT1939EDD is suitable for applications in automotive, industrial, and communication systems requiring flexible and efficient power conversion.
