High power COT switching controller delivers one percent output accuracy
The device is designed to achieve excellent transient response and output accuracy using Exar’s proprietary emulated current mode Constant On-Time (COT) control loop. The XRP6141 delivers core voltage rails for ASICs, FPGAs, DSPs and Network Processors in communications, networking and industrial markets.
The device is specified with a wide input voltage range of 4.5 V to 22 V and delivers an adjustable output voltage from 0.6 V to 18 V. With its exceptional 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. Additionally, the XRP6141 offers a host of supervisory and protection features for proper sequencing, safe operation under abnormal operating conditions and light load operation.
Availability and Pricing
The XRP6141 is available now in a RoHS compliant, green/halogen free space-saving 16-pin 3×3 QFN package and is priced from $1.29 in 1000 piece quantities.
