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 150kHz to 650kHz programmable operating frequency that can be either adjusted with an external resistor or synchronized with an...
