GENERAL DESCRIPTION
The XRP6657 is a high efficiency synchronous
step down DC to DC converter capable of
delivering up to 1.5 Amp of current and
optimized for portable battery-operated
applications.
Operating over an input voltage range of 2.5V
to 5.5V, it provides an adjustable regulated
output voltage down to 0.6V. The XRP6657
uses a constant 1.3 MHz frequency pulse width
modulation (PWM) scheme allowing for
compact external components, low output
voltage ripple and fixed frequency noise, while
Pulse Skip Mode (PSM) is used to improve
light load efficiency. A low dropout mode
provides 100% duty cycle operation.
The solution footprint is further reduced by a
current mode internal compensation network
and built-in synchronous switch removing the
need for an external Schottky. Over-current
and over-temperature protection insures safe
operations under abnormal operating
conditions.
The XRP6657 is available in a compact RoHS
compliant “green”/halogen free thin 6-pin DFN
package.
