MAX15004A/B/C/D-MAX15005A/B/C/D 4.5V to 40V Input Automotive Flyback/Boost/SEPIC Power-Supply Controllers Data sheet
■The MAX15004/MAX15005 high-performance, current-mode 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 boot-strapped to a boosted output voltage. The controllers integrate all the building blocks necessary for implementing fixed-frequency isolated/nonisolated power supplies. The general-purpose boost, flyback, forward, and SEPIC converters can be designed with ease around the MAX15004/MAX15005.The current-mode control architecture offers excellent line-transient response and cycle-by-cycle current limit while simplifying the frequency compensation. Programmable slope compensation simplifies the design further. A fast 60ns current-limit response time, low 300mV current-limit threshold makes the controllers suitable for high-efficiency, high-frequency DC-DC converters. The devices include an internal error amplifier and 1% accurate reference to facilitate the primary-side regulated, single-ended flyback converter or nonisolated converters.An external resistor and capacitor network programs the switching frequency from 15kHz to 500kHz (1MHz for the MAX15005). The MAX15004A/MAX15005 provide a SYNC input for synchronization to an external clock. The maximum FET-driver duty cycle for the MAX15004A/B/C/D is 50%. The maximum duty cycle can be set on the MAX15005A/B/C/D by selecting the right combination of RT and CT.The input undervoltage lockout (ON/OFF) programs the input-supply startup voltage and can be used to shutdown the converter to reduce the total shutdown current down to 10μA. Protection features include cycle-by-cycle and hiccup current limit, output overvoltage protection, and thermal shutdown.The MAX15004/MAX15005 are available in space-saving 16-pin TSSOP and thermally enhanced 16-pin TSSOP-EP packages. All devices operate over the -40°C to +125°C automotive temperature range.
