The MAX5094 CMOS, high-performance, current-mode PWM controller has all the features required for isolated/non-isolated power supplies with a wide input voltage range. These controllers are ideal for low and high power general purpose and telecom power supplies. The MAX5094 contains a fast comparator with a typical delay from the current sense terminal to the output of only 60ns for overcurrent protection. The MAX5094 contains an error amplifier that generates the output at COMP. Soft-start can be achieved using external components to control the rise of the COMP voltage. The oscillator frequency can be adjusted from 20kHz to 1MHz by external resistors and capacitors. The discharge current of the timing capacitor is fine-tuned to set the dead time and maximum duty cycle at a given frequency. The sawtooth wave output from the RTCT terminal can be used for slope compensation when needed.

Pin-compatible with UCC28C43 (MAX5094A) and UCC28C45 (MAX5094B), drop-in replacement; 2A source and 1A sink drive capability; up to 1MHz switching frequency; bidirectional frequency synchronization (MAX5095A/MAX5095B); advanced output drive Used for secondary-side synchronous rectification (MAX5095C); 60ns fast cycle-by-cycle current limiting; fine-tuned oscillator capacitor discharge current to precisely set maximum duty cycle; with 0.8V hysteresis, start-up voltage accurate to ±5% ; 32μA low start-up current; 5V regulator output (REF), 20mA drive capability; 0.3V current-sense threshold version; thermal shutdown.
