Exar XRP7724 Digital PWM/PFM Step Down Controller
Exar XRP7724 Quad Channel Digital PWM (Pulse Width Modulator / PFM (Pulse Frequency Modulator) Step Down Controller is the world's lowest power consumption digital PWM / PFM device. XRP7724 is the first digital controller that can be considered for portable or other power-sensitive applications due to the significant reduction in operating current. Patented technology allows transient performance equivalent to the fastest comparator-based analog technologies, ensuring output capacitor size is kept to a minimum. This Exar step down controller includes three power switch IOs for driving load disconnect MOSFETs. XRP7724 is ready for the next generation of FPGAs and Processors using advanced energy management voltage control by providing output voltage resolution programming as fine as 2.5mV. Each output voltage can be programmed from 0.6V to 5.5V without the need for any external components.
