The MAX1856EUB+T is a versatile PWM SLIC power supply controller designed by Analog Devices. It offers a low-cost solution for generating various output voltages, including -24V and -72V for SLIC applications, -48V for IP phones, and negative voltages up to -185V for MEMS bias supplies. The device operates from a wide input voltage range of 3V to 28V, making it suitable for cost-sensitive applications like xDSL, cable modems, and set-top boxes.
Key features include adjustable switching frequency from 100kHz to 500kHz, clock synchronization capability, and internal soft-start. The flyback topology ensures high transformer utilization and low ripple current. The MAX1856EUB+T provides low audio-band noise on talk battery and can handle ring trip transients. It is supplied in a compact 10-pin uMAX package suitable for surface mounting.
This controller is ideal for applications requiring reliable and efficient power generation for telecommunications equipment and broadband consumer premises equipment (CPE). Its design considerations include the use of off-the-shelf transformers and current-mode control for accurate regulation and overcurrent protection.
