your ? electronic ? engineering ? resource ? ? xrp7708 quad channel digital pwm step down controller general description: the xrp7708 is a quad-output pulse-width modulated (pwm) step-down dc-dc controller with a built-in ldo for standby power and gpios. the device provides a complete power management solution in one ic and is fully programmable via an i2c serial interface. independent digital pulse width modulator (dpwm) channels regulate output voltages and provide all required protection functions such as current limiting and over-voltage protection. each output voltage can be programm ed from 0.9v to 5.1v without the need of an external voltage divider. the wide ran ge of the programmable dpwm switching frequency (from 300 khz to 1.5 mhz) enables the user to opti mize between efficiency and component size. input voltage range is from 6.5v to 20v.two controllers support a load of up to 5a,while the other two controllers support up to 8a. i2c bus interface is provided to program the ic as well as to communicate with the host for fault reporting and handling, power rail parameters monitoring, etc. the devic e offers a complete solution for softstart and soft-stop. the start-up delay and ramp of each pwm regulator can be independently controlled. the device can start up a pre-biased pwm channel without causing large negative inductor current. key features: ? 4 channel step down controller o 2 x 5a channels & 2 x 8a channels o programmable output voltage 0.9v-5.1v o programmable 1.5mhz dpwm frequency legal disclaimer: the content of the pages of this website is for your general information and use only . it is subject to change without notice. from time to time, this website may also include links to other websites. these links are provided for your convenience to provide further information. they do not signify that we endorse the website(s). we have no responsibility for the content of the linked we bsite(s). your use of any information or materials on this website is entirely a t your own risk, for which we shall not be liable. it shall be your own responsibility to ensure that any products, services or information availa ble through this website meet your specif ic requirements.
