MAX1856EUB Description

Short technical summary and product information.

The MAX1856EUB is a versatile PWM SLIC power supply controller from Analog Devices, offering a low-cost solution for generating essential power supplies. It supports a wide input voltage range from 3V to 28V and can generate various output voltages, including -24V and -72V dual outputs, -48V for IP phones, and negative voltages up to -185V for MEMS bias supplies. The switching frequency is adjustable from 100kHz to 500kHz, with options for clock synchronization for noise-sensitive applications.

 

Designed for cost-sensitive applications, the MAX1856EUB operates from a low-cost, unregulated DC power supply. It is suitable for use in xDSL, cable modems, set-top boxes, LMDS, MMDS, WLL, and FTTH CPE. The controller provides low audio-band noise for talk battery and can handle ring trip conditions. Its flyback topology ensures high transformer utilization and low ripple current. The device features internal soft-start and current-mode control, eliminating the need for external loop compensation.

 

The MAX1856EUB is available in a compact 10-pin uMAX package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions.
