80W Eighth-brick Isolated DC-DC Converter LES B Series
The LES B series of eighth-brick isolated DC-DC converters comprises eigth single output models offering fully regulated voltages of 1 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V or 12.0 V. These converters can deliver up to 25 amps and up to 80 watts of output power, depending on the particular model. They have a wide 2:1 input range of 36 to 75 Vdc and are designed primarily for use with standard 48 V telecommunications equipment supplies. LES B series converters have a typical efficiency of up to 92% and accommodate an ambient operating temperature range of -40 to 85˚C. Their open-frame design is optimized for forced air or conduction cooling and there is a choice of surface-mount or through-hole terminations. The conversion technology employs 500 kHz fixed frequency switching to help minimize external EMI filtering requirements. Standard features include output trim, remote enable, undervoltage lockout and differential remote sense, with non-latching overvoltage and overtemperature protection. LES B series converters have an installed height of just 0.33 inch (8.4 mm), making them ideal for systems with demanding inter-board spacing requirements.
