GENERAL DESCRIPTION
The XRP6658 is a synchronous current mode
PWM step down (buck) converter capable of
delivering up to 1Amp 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 component count and
solution footprint. It provides 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 quiescent current
supports the most stringent battery operating
conditions.
Built-in over temperature and under voltage
lock-out protections insure safe operations
under abnormal operating conditions.
The XRP6658 is offered in a RoHS compliant,
“green”/halogen free 5 -pin SOT23 package.
