DESCRIPTION

Independent 1% Reference

The UC3838 and the UC3838A family of magnetic

amplifier controllers contains 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.

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

The UC3838A originally was a parametric

improvement version of the UC3838 which since

has been used for both versions. There is no

difference between the UC3838A and UC3838

version.

By controlling the reset current to a magnetic

amplifier, this device defines the amount of

volt-seconds the magnetic amplifier blocks before

switching to the conducting state. Magnetic

amplifiers are ideal for post-regulators for

multiple-output power supplies where each output

can be independently controlled with efficiencies

up to 99%. With a square or pulse-width

modulated input voltage, a magnetic amplifier

blocks a portion of this input waveform, allowing

just enough to pass to provide a regulated output.

With the UC3838/A, only the magnetic amplifier

coil, three diodes, and an output L-C filter are

necessary to implement a complete closed-loop

regulator.
