TB9911, TB9911-Top, Switch-Mode LED Driver
The TB9911 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost, buck-boost, or SEPIC), in a constant frequency or constant off-time mode.
The controller uses a peak current control scheme, (with programmable slope compensation), and includes an inter
