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.
