The ALD15 Series is the latest addition to the Sixteenth-brick DC-DC converters. It 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. It comes with industry standard features such as Input UVLO; Output Enable; non-latching OCP, OVP and OTP; Output Trim; Differential Remote Sense pins. It’s an open frame low profile design which comes either through-hole or surface mount termination. Ideal for use with telecom-standard 48 V power supplies, the converters are capable of achieving up to 92 percent 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.
