The XRP6141 provides core voltage rails for ASICs, FPGAs, DSPs and network processors in communications, networking and industrial markets; it is specified with a wide input voltage range of 4.5V to 22V and delivers an adjustable output voltage from 0.6V to 18V. With its 0.1% line regulation across the entire input voltage range and 1% output accuracy over full temperature range, XRP6141 provides increased headroom to engineers for easier design implementations.

The emulated current mode COT control scheme has the fast transient response of conventional COT control loops without any of the compromises. Exar’s COT control loop enables operation with ceramic output capacitors, eliminating loop compensation, which simplifies system design and reduces overall component count. The XRP6141 offers supervisory and protection features for proper sequencing, safe operation under abnormal operating conditions and light load operation.

In a 16-pin 3 x 3 mm QFN package it is priced from $1.29 (1000).
