MAX15005AAUE+

The MAX15005AAUE+ is a 4.5V to 40V input automotive flyback/boost/SEPIC power supply controller in 16 pin TSSOP package. This current-mode PWM controller operates at an automotive input voltage range from 4.5V to 40V (load dump). The input voltage can go lower than 4.5V after start-up if IN is bootstrapped to a boosted output voltage. The controller integrates all building blocks necessary for implementing fixed-frequency isolated/nonisolated power supplies. General-purpose boost, flyback, forward and SEPIC converters can be designed with ease around the IC. The input undervoltage lockout (ON/OFF (complementary)) programs the input-supply start-up voltage and can be used to shutdown the converter to reduce total shutdown current down to 10µA. Protection features include cycle by cycle and hiccup current limit, output over-voltage protection and thermal shutdown. It is used in vacuum fluorescent display (VFD) power supply, isolated flyback, forward, nonisolated SEPIC, boost converters.
