Maxim MAX1500WETN

Overview

The MAX15000AEUB+ from Maxim Integrated Products is a current-mode PWM controller with programmable switching frequency in 10 pin µMAX package. It contains an internal error amplifier that regulates the tertiary winding output voltage which is used in primary-side-regulated isolated power supplies. Primary-side regulation eliminates the need for an optocoupler. An input undervoltage lockout is provided for programming the input-supply start voltage and to ensure proper operation during brownout conditions. An open-drain UVLO flag output with 210µs internal delay, allows the sequencing of a secondary-side controller. The input-supply start voltage is externally programmable with a voltage-divider. A UVLO/EN input is used to shutdown the MAX15000. The MAX15000AEUB+ has an internal bootstrap UVLO with large hysteresis that requires a minimum 23.6V for start-up.
