Hot-selling and scarce ZSPM1363BA1R1 True Digital PWM Datasheet Controller QFN spot stock

Product Descriptions

The ZSPM1363  is  a configurable true-digital dualphase PWM controller for high-current, non-isolatedDC/DC supplies . It operates as a synchronous stepdown converter in a single-rail and dual-phase configuration .

The ZSPM1363 integrates a digital control loop, optimized for maximum flexibility and stability, as well asload step and steady-state performance . In addition,a rich set of protection and monitoring functions isprovided . On-chip, non-volatile memory (NVM) andan I²C interface facilitate configuration .

The PC-based IDT Pink Power Designer™ graphicaluser  interface  (GUI)  provides  a  user-friendly  andeasy-to-use  interface  to  the  device  for  communication  and  configuration .   It  can  guide  the  userthroug h the design of the digital compensator andoffers  intuitive configuration  methods for additionalfeatures, including protection and sequencing .
