The XRP6670 is a synchronous current mode PWM step-down (buck) regulator capable of delivering up to 3Amps of current. A 2.6V to 5.5V input voltage range allows for single supply operation from industry standard 3.3V and 5V power rails.

Based on a current mode PWM control scheme, the XRP6670 operating frequency is programmable between 300kHz and 2.5MHz via an external resistor. This flexibility allows the XRP6670 to optimize component selection and reduce component count and solution footprint. It provides a low output voltage ripple, excellent line and load regulation and has a 100% duty cycle LDO mode. Output voltage is adjustable to as low as 0.8V with a better than 2% accuracy while a low quiescent current supports the most stringent battery operating conditions.

Built-in over temperature, overcurrent, short-circuit and undervoltage lock-out protections insure safe operations under abnormal operating conditions.

The XRP6670 is offered in a RoHS compliant, "green"/halogen free 3mm x 3mm 10-pin DFN package.
