MAX5071AASA-T 产品详情

The MAX5070/MAX5071AASA+T BiCMOS, high-performance, current-mode PWM controllers have all the features required for wide input voltage range isolated/nonisolated power supplies. These controllers are used for low- and high-power universal input voltage and telecom power supplies. The MAX5070/MAX5071AASA+T contain a fast comparator with only 60ns typical delay from current sense to the output for overcurrent protection. The MAX5070A/MAX5070B have an integrated error amplifier with the output at COMP. Soft-start is achieved by controlling the COMP voltage rise using external components. The 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 MAX5071A/MAX5071B 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 pins of all devices together. When synchronizing with other devices, the MAX5071A/MAX5071B with the highest frequency synchronizes the other devices. Alternatively, the MAX5071A/MAX5071B can be synchronized to an external clock with an opendrain output stage running at a higher frequency. The MAX5071C provides a clock output pulse (ADV_CLK) that leads the driver output (OUT) by 110ns. The advanced clock signal is used to drive the secondary-side synchronous rectifiers. The MAX5070/MAX5071AASA+T are available in 8-pin μMAX and SO packages and operate over the automotive temperature range of -40°C to +125°C.
