XRP6658
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 component 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 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.
