UWE series DC/DC converters

Murata has extended its UWE series of eighth-brick, 4:1 ultra-wide input isolated DC/DC converters with the addition of two models.

Both the UWE-5/15-Q48N-C (15 A at 5 VDC) and the UWE-15/5-Q12P-C (5 A at 15 VDC) provide up to 75 W of power, making them suitable space-saving, drop-in replacements for commonly used 100 W quarter-brick devices where the full 100 W is not needed.

The ultra-wide input voltage range of 18 to 75 DC (UWE-5/15-Q48N-C) and 9 to 36 DC (UWE-15/5-Q12P-C) is available. Typical applications include mobile and battery-powered devices, test equipment, telecoms and wireless, plus distributed power architectures in the industrial, high reliability, aerospace, networking and wireless, and telecom and office equipment markets.

The series has a synchronous rectifier design that gives a typical efficiency rating of 90%, plus low power dissipation with no reverse output conduction. This allows the converters to be used without fans or temperature derating in most applications.

The series provides 1500 VDC isolation (basic insulation) to ensure safety and fully differential (floating) operation for maximum application flexibility. All models include remote on/off control, trim and remote sense functions to provide compensation for line drop errors at high output currents.

Self-protection design features including pre-bias operation, input undervoltage and output short circuit, overcurrent and overtemperature protection prevent potential damage to both the converter and outside circuits.
