资 源 简 介
The XRP9710 and XRP9711 are programmable step down power modules providing two 6A outputs. The module package contains the switching controller， power MOSFETs， inductors and support components. As a result， external components are minimal. A wide input voltage range （4.75V to 5.5V or 5.5V to 22V） allows for single supply operaTIon from standard power rails. The modules measure only 12x12x2.75mm making it half the size of compeTIng 12V capable 6Amp modules. The 2.75mm height allows them to be placed on the back of boards or under heat sinks where other soluTIons cannot， yet they contain two full 6A buck power stages and two Digital Pulse Width Modulator （DPWM） controllers with gate drivers. Designed to operate at a constant PWM switching frequency between 500kHz and 750kHz， the Digital Pulse Frequency Mode （DPFM） results in better than 80% efficiency at light load currents and low operaTIng current allow for portable and Energy Star compliant applications. Each XRP9710 or XRP9711 output can be individually programmed to as low as 0.6V with a resolution as fine as 2.5mV， and configurable for precise soft start and soft stop sequencing， including delay and ramp control. The XRP9710/1 is fully controlled via a SMBuscompliant I2 C interface allowing for advanced local and/or remote reconfiguration， full performance monitoring and reporting as well as fault handling. Built-in output over-voltage， overtemperature， over-current and under voltage lockout protections insure safe operation under abnormal operating conditions. The XRP9710/1 is offered in a RoHS compliant， halogen-free LGA package.
