    Products Detail

    The PTB4851x series are dual complementary-output DC/DC converters designed for xDSL telecom applications. They operate from a standard telecom (-48 V) central office supply and provide up to 72 W of power in a balanced load configuration. The modules feature dual complementary outputs (±5V, ±12V, or ±15V), input voltage range of 36V to 75V, 1500V DC isolation, overcurrent protection, overtemperature shutdown, and undervoltage lockout. The PTB48511 adds output overvoltage protection. They include an on/off enable control for sequencing and can synchronize with PTB48500 modules. The modules use double-sided surface mount technology and are available in both through-hole and surface mount pin configurations without requiring a heatsink.

    Key Features

    • Dual complementary outputs (±5V, ±12V, or ±15V), Input voltage range: 36V to 75V, On/Off enable for sequencing, 1500V DC isolation, Overcurrent protection, Overvoltage protection (PTB48511 only), Overtemperature shutdown, Undervoltage lockout, Temperature range: -40°C to 85°C, Industry standard outline, Fixed frequency operation, Synchronizes with PTB48500, Safety approvals: EN60950, UL/cUL60950

    Application scenarios

    • xDSL telecom applications
    • line-driver devices
    • AC-7 ADSL chipset
    • analog applications requiring complementary supply with balanced loads
