High-Performance, Single-Ended, Current-Mode PWM Controllers
General Description
The MAX5070/MAX5071 Bi
CMOS, 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/MAX5071 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 compone...
