Hi,
I am looking for a low cost PWM controller for a buck boost converter (or flyback converter), that is commonly available in electronics stores in Bangalore/India. The design is targeted at highly cost sensitive markets, so I need a controller IC accordingly. Input voltage range is 6 to 30Volts. Converter power outputs are 15W, 25W & 50W. The controller should support duty cycles of >50% for operation in continuous conduction mode. Please recommend some common options from TI that are easily available in India?
Regards,
Rajaram
