The output is ideal for powering non-isolated, point-of-load converters such as synchronous buck converters used commonly in Intermediate Bus Architectures. The QBC is a highly efficient, cost-effective, low profile, single-output DC/DC converter in an industry-standard, quarter-brick footprint. The standard feature set includes remote on/off, remote output voltage sensing, positive output trim, input undervoltage lockout, and overtemperature shutdown with hysteresis.
