GENERAL DESCRIPTION
The MAX5094 has an integrated error amplifier with the output at COMP. Softstart is achieved by controlling the COMP voltage rise using external components. The oscillator frequency is adjustable from 20kHz to 1MHz with an external resistor and capacitor. The timing capacitor discharge current is trimmed allowing for programmable dead time and maximum duty cycle for a given frequency. The available saw-toothed waveform at RTCT can be used for slope compensation when needed. The MAX5095A/MAX5095B include a bidirectional synchronization circuit allowing for multiple controllers to run at the same frequency to avoid beat frequencies. Synchronization is accomplished by simply connecting the SYNC of all devices together. When synchronizing with other devices, the MAX5095A/MAX5095B with the highest frequency synchronizes the other devices. Alternatively, the MAX5095A/MAX5095B can be synchronized to an external clock with an open-drain output stage running at a higher frequency.
