The UC3845AD8 is an integrated circuit manufactured by Texas Instruments. It is a pulse width modulated (PWM) current mode oscillator used in DC-to-DC switched mode converter units. The IC includes multiple functional blocks such as an oscillator, an error amplifier, a programmable reference, a comparator, and an output logic circuit. It is designed for high precision and offers a wide range of features, such as automatic recovery from faults, synchronizable oscillator, and soft-start. The oscillator is designed for inductive or capacitive loads operation and its frequency operating range is adjustable from 10 kHz to 1 MHz. The IC is rated for operation from a +5V to +38V voltage supply and its power dissipation is up to 0.7W. The IC package comes in a SOIC-8 or DIP-8 configuration.
