IS31PM3510
DESCRIPTION
The IS31PM3510 is an asynchronous multi-topology PWM controller that employs a single inductor to provide excellent voltage regulation. In a Buck-Boost topology regulated output voltage is maintained when the input voltage is either less or greater than the desired output voltage. With a 150k Hz to 650k Hz programmable operating frequency that can be either adjusted with an external resistor or synchronized with an external clock, optimum inductor and capacitor (s) size can be achieved while maintaining high efficiency. The controller integrates spread spectrum function that effectively reduces overall EMI profile.
The IS31PM3510 can also be configured for either Buck or Boost operation with a single switch, and features robust protection functions with power good signal output, PGOOD, for MCU fault flag reporting.
The IS31PM3510 is available in an e TSSOP-16 package with an exposed thermal pad for enhanced thermal dissipation.
