Maxim Integrated MAX15004 PWM Controllers
Maxim Integrated's MAX15004A and MAX15004B high-performance, current-mode PWM controllers operate down to 2.5V input voltage after startup and include output overvoltage protection for Vacuum Fluorescent Displays (VFDs). Maxim Integrated MAX15004 PWM controllers integrate all the building blocks necessary to for implementing fixed-frequency isolated/non-isolated power supplies. General purpose boost, flyback, forward, and SEPIC converters can be designed with ease around the MAX15004. The current-mode control architecture offers excellent line-transient response and cycle-by-cycle current limit while simplifying the frequency compensation. Programmable slope compensation simplifies the design further. A fast 60ns current-limit response time, low 300mV current-limit threshold makes the controllers suitable for high-efficiency, high-frequency DC-DC converters. The devices include an internal error amplifier and 1% accurate reference to facilitate the primary-side regulated, single-ended flyback converter or non-isolated converters.
