About this product
The UC3844 is a fixed-frequency current-mode PWM controller with under-voltage lockout, a trimmed reference, a PWM comparator with current limit and a totem-pole output for driving N-channel MOSFETs. It is used in off-line and DC-DC switch-mode power supplies with a minimal external parts count. Its start-up current is below 1 mA.

Which power switch does the UC3844 drive?
Its totem-pole output is designed to drive N-channel MOSFETs directly, which are the usual power switches in flyback and forward converter designs.
What does under-voltage lockout do?
UVLO keeps the output disabled until the supply voltage rises above its start threshold, and it shuts the output off if the supply drops too low. This prevents erratic switching during power-up and power-down.
