Analog Devices / Maxim Integrated MAX15005DAUE/V+ PWM Controllers

Analog Devices Inc. MAX15005DAUE/V+ PWM Controllers operate at an automotive input voltage range from 4.5V to 40V (load dump). The input voltage can go lower than 4.5V after startup if IN is bootstrapped to a boosted output voltage. The controllers integrate the building blocks necessary for implementing fixed-frequency isolated/non-isolated power supplies. The general-purpose boost, flyback, forward, and SEPIC converters are designed around the MAX15004/MAX15005.
