SIMPLIFIED SCHEMATIC GATE DRIVE OPTO ISOLATION Control Reference, trim & Error Amplifier +VIN +VOUT –VOUT –VIN On/Off Control TRIM ISOLATION BARRIER Typical topology is shown. Typical unit Wide range 4:1 inputs on the 0.92" x 1.92" x 0.35" converter are either 9 to 36 Volts DC (Q12 models) or 18 to 75 Volts DC (Q48 models), ideal for battery-powered and telecom equipment. Fixed output voltages from 3.3 VDC to 15 VDC are tightly regulated and may be trimmed within ±10% of nominal output. Applications include small instruments, computer-based systems, data com- munications equipment, remote sensor systems, vehicle and portable electronics. The UEI 30W Series includes full magnetic and optical isolation up to 2250 Volts DC (basic insulation), Q48 models. For connection to digital systems, the outputs offer fast settling to current step loads and tolerance of higher capacitive loads. Excellent ripple and noise specifications assure compatibility to circuits using CPU’s, ASIC’s, programmable logic and FPGA’s. No minimum load is required. For systems requiring controlled startup/shutdown, an external switch, transistor or digital logic may be used to activate the remote On/Off control. Remote Sense inputs compensate for resistive line drops at high currents. A wealth of self-protection features avoid both converter and external circuit problems. These include input undervoltage lockout and overtem- perature shutdown. The outputs current limit using the “hiccup” autorestart technique and the outputs may be short-circuited indefinitely. Additional features include output overvoltage and reverse conduction elimination. The synchronous rectifier forward topology offers high efficiency for minimal heat buildup and “no fan” operation.
