TPS61165: Buck type LED driver with analog dimming by PWM input

Part Number:TPS61165

 Hi guys,

 My customer is looking for a buck converter type LED driver IC like TPS61165 dimming method.

 TPS61165 boost LED driver with dimming control by output current changing. But in the device case, the output current value can be controlled by PWM signal because the PWM duty is converted to output current value internally.

 The customer don't want to use chopped output current for LED because the light source is used for a video camera and the chopped output current causes flickering in the video.

 So could you please tell me any buck type LED driver IC which can control the output current without chopping by PWM signal duty ratio?

 Your reply would be appreciated.

 Best regards,

 Kazuya Nakai.
