Products Detail

The UC3838 and UC3838A family of magnetic amplifier controllers contain the circuitry to generate and amplify a low-level analog error signal along with a high voltage-compliant current source. This source provides the reset current necessary to enable a magnetic amplifier to regulate and control a power supply output in the range of 2 A to 20 A. The device includes a precision 2.5-V reference, two uncommitted high-gain operational amplifiers, and a high-gain PNP-equivalent current source which can deliver up to 100 mA of magnetic amplifier reset current and with –120-V capability. It is available in plastic batwing DIP, wide body SOIC, and PLCC packages.

Key Features

Independent 1% Reference, Two Uncommitted Identical Operational Amplifiers, 100-mA Reset Current Source With -120-V Capability, 5-V to 40-V Analog Operation, 5-W DIP Package, Precision 2.5-V Reference, High-gain PNP-equivalent Current Source, Available in Plastic Batwing DIP, Wide Body SOIC, and PLCC Packages

Application scenarios

Post-regulators for multiple-output power supplies
