Datasheet Summary
1A 1.5MHz PFM/PWM Synchronous Step-Down Converter
January 2014
GENERAL DESCRIPTION
The XRP6658 is a synchronous current mode PWM step down (buck) converter capable of delivering up to 1 Amp of current and optimized for portable battery-operated applications.
Based on a current mode 1.5MHz constant frequency PWM control scheme, the XRP6658 reduces the overall ponent count and solution footprint as well as provides a low output voltage ripple and excellent line and load regulation. It also implements a PFM mode to improve light load efficiency as well as a 100% duty cycle LDO mode. Output voltage is adjustable to as low as 0.6V with a better than 3% accuracy while a low...
