AT9933 Datasheet and Design for a Boost-Buck Converter Circuit

 AT9933 Datasheet and Design for a Boost-Buck Converter Circuit - AT9933 variable frequency PWM controller IC used to be applied on automotive LED lighting to control lamp driver using Design Example of Boost-Buck Converter Circuit Diagrama low noise boost buck topology. 

And herein a picture perform a design example circuit for the converter using AT9933, in the end you are provided with the datasheet.

In the AT9933 datasheet, there are sections explained such as :

1. the power topology (boost-buck DC/DC converter), 
2. input voltage regulator function, 
3. setting the minimum input voltage at VIN pin, 
4. reference used to set the current thresholds of comparators, 
5. current comparators feature, achieving PWM dimming, adding over-voltage protection, 
6. build a damping circuit, and input and output current limits.
