Look for multi-channel PWM signal output chip

Hi Cickey,

For multi-channel buck controllers with I2C control, we have:
TPS53681 (Dual-Channel 6+2/5+3 D-CAP+TM Multiphase Step-Down Controller with PMBus and NVM)
TPS40428 (Dual Output, 2-Phase, Stackable PMBus Synchronous Buck Driverless Controller)
TPS40422 (Dual Output or Multiphase Synchronous Buck Controller with PMBus)

If dual channel is not enough for you, you can use a controller to work with multiple gate driver to drive each channel, but the number of outputs is limited by the controller...

BTW, we have TPS65400, 4A/4A/2A/2A 4 channel buck converter with I2C control. Is it suitable for your application?

Thanks!

Hi,Sam,
this type cant meet my customer's demant, they want to look for one pwm input and multiple complementary pwm outputs.
do we have like this?

Hi,

Seems what you need is multi-channel gate drivers.
You may take a look at TPL7407LA (30-V 7-Channel Low Side Driver).

hi，
this also cant meet demand，we need one PWM input ，and two or more complementary PWM output channel.
for example,when input terminal is given a pwm signal,the output terminal can output two pwm signals ,and the two pwm signal is complementary,emphasize again,be complementary.
surely,if can output more complementary pwm signal,we prefer.
