PTB48502A 3.3/1.2V 45W 输出 48V 输入的 DC/DC 转换器

PTB48502A 描述

The PTB4850x power modules are a dual-output isolated DC/DC converter, designed to provide the logic supply voltages for AC-7 based xDSL applications. The PTB48500 is rated for 13 A of total output current, making it suitable for 32-channel xDSL applications. The PTB48501 and PTB48502 provide output current for powering up to 64 xDSL channels. The PTB48501 is rated for 16.5 A total output current, and the PTB48502, 21 A. The PTB48502 incorporates 10 W of additional capacity for powering peripheral circuitry. Any of these converters can be used for other applications with similar power requirements.

The modules operate from a standard telecom (-48 V) central office (CO) supply and include an on/off enable control, output current limit, over-temperature protection, input under-voltage lockout (UVLO).
