UCC28084 - 8-Pin Current Mode Push-Pull PWM Controllers

Download the UCC28084 datasheet PDF. This datasheet also covers the UCC28083 variant, as both devices belong to the same 8-pin current mode push-pull pwm controllers family and are provided as variant models within a single manufacturer datasheet.

Description

The UCC38083/4/5/6 is a family of BiCMOS pulse width modulation (PWM) controllers for dc-to-dc or off-line fixed-frequency current-mode switching power supplies.

The dual output stages are configured for the push-pull topology.
