The PTB48500 is rated for 13 A of total • 1500 VDC Isolation output current, making it suitable for 32-channel • Over-Current Protection xDSL applications. The PTB48501 and PTB48502 provide output current for powering up to 64 xDSL • Over-Temperature Shutdown channels. The PTB48501 is rated for 16.5 A total • Under-Voltage Lockout output current, and the PTB48502, 21 A. The • Fixed Frequency Operation PTB48502 incorporates 10 W of additional capacity for powering peripheral circuitry. Any of these • Temp Range: –40 °C to 85°C converters can be used for other applications with • Industry Standard Outline similar power requirements. • Operates with PTB4851x for Complete AC7 The modules operate from a standard telecom Power Solution (–48 V) central office (CO) supply and include an • Powers up to 64 DSL Ports on/off enable control, output current limit, over-temperature protection, input under-voltage • Safety Approvals: lockout (UVLO). The PTB48500 and PTB48501 also – UL/cUL 60950 incorporates a power-up reset (POR) output. – EN 60950 The modules are designed to operate with one of the PTB4851x DC/DC converter modules. The combination of PTB4850x and PTB4851x converter provides the complete the power supply for an AC7 chipset. The EN Out and Sync Out pins provide compatible output signals for controlling both the power up sequence and switching frequency the PTB48510. The PTB4850x modules employ double-sided surface mount construction, and are an industry standard size.
