ALD12/15/18/20/25 Series 1/16th Brick Converters


Open frame, low profile DC-DC power converters from Emerson


Emerson Network Power's ALD12/15/18/20/25 Series 1/16th Brick Converters Emerson's ALD15 operates from an input range of 36 to 75 V and provides fully regulated output voltages of 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V, and 12.0 V rated up to 35 W. Included are industry standard features such as input UVLO, output enable, non-latching OCP, OVP and OTP, output trim, and differential remote sense pins. It has an open frame low profile design and comes in either through-hole or surface mount termination. Ideal for use with telecom-standard 48 V power supplies, ALD15 converters are capable of achieving up to 91% efficiency at full load, and are extremely cost-effective when used in applications requiring up to 35 W of output power. The low profile ALD15 series has an installed height of just 0.35 inches, making it ideal for systems that require tight inter-board spacing or where sufficient separation between the converter and adjacent boards is needed.

The ALD12/18/20/25 series operate from an input voltage range of 36 V to 75 V, and provide 6 configured outputs from 1.2 V to 5 V. It delivers up to 25 A max current at 1.8 V and lower, offering impressive levels of efficiency. The series comes with industry standard features such as input UVLO, non-latching OCP, OVP and OTP, output trim, and differential remote sense pins. With its wide operating temperature range of -40°C to 85°C ambient, ALD12/18/20/25 converters are deployable into almost any environment. Datasheet
