AT9933 General Description

The AT9933 is a variable frequency PWM controller IC, designed to control an LED lamp driver using a low-noise boost-buck (Ćuk) topology. The AT9933 uses patent-pending hysteretic current-mode control to regulate both the input and the output currents. This enables superior input surge immunity with.
