Murata’s new IRH250W80 half brick and IRQ150W80 quarter brick DC/DC converters

Murata announces two new ultra wide 10:1 ratio DC/DC converters from Murata Power Solutions.

The IRH250W80 250w half brick and the IRQ150W80 150w quarter brick feature an ultra-wide DC input operating voltage range of 16v - 160v DC. The converters feature an operating baseplate temperature range of -40c - +100c. Single output voltage models are available of 12v, 24v, 54v with an input to output galvanic isolation of 4242vDC.

The new converters enable ON/OFF to switch the module on and off remotely. Available single O/P 150w or 250w (12v,24v,54v) variants covers all major application voltages. To prevent deep discharge of Supplying batteries, the converters feature adjustable under voltage lockout protection. Thanks to the ultra-wide DC i/p voltage range from 16.8v to 160v, they can operate from all rail batteries (24v, 36v, 48v, 72v, 110v). Their remote sense function compensates for voltage drops and a hold up capacitance pin provides hold up during critical transients or brownouts. For external circuitry, a charge pump signal is provided by the pulse out feature. With an over current protection adjustment, the new converters also protect the circuitry against fault conditions. A trim adjustment pin provides +/-10 percent adjustment range. Additional features include positive or negative enable, self-protection to external short circuits and over temperature protection with self-resetting ability.

All these features make the new IRH250W80 Half Brick and IRQ150W80 Quarter Brick DC/DC Converters the ideal solution for railway, e-mobility and industrial applications.
