Part Number: TPS61165
we use the tps61165 logic pwm mode to control the light.
but as the figure show, the 1.8V*(1-D)
D is the control pwm duty, and the output is current, it is not directly proportional to the duty-cycle.
But the CTRL is high…
Part Number: TPS61165 Regarding the operation of the TPS61165:
Will the IC operate correctly if the voltage at the VIN pin rises to the specified level starting from approximately 1.5V, rather than from 0V?
(In other words, will the IC function properly…
Part Number: TPS61165 Hi Support,
I have a 10 white LED serious driver with TPS61165, the input voltage is 6.5V and the output current is 20mA. When I have the CTL driven by PWM, everything works fine with expected current.
But when I pull the CTL…
Part Number: TPS61165
Summary: In a boost LED driver application, the FB pin regulates well above the datasheet-specified 196–204 mV (typ. 200 mV) reference, and the amount by which it overshoots depends on the input voltage. At a higher input voltage…
Part Number: TPS61165 Hello,
I’m currently designing a LED backlight driver for an LCD panel using the TPS61165 , and I would appreciate your help reviewing both my schematic and PCB layout .
Here are the main parameters of the LCD backlight:
…
Part Number: TPS61165 "The circuit is not working as expected. When applying a 20 kHz PWM signal at a 50% duty cycle, the LED brightness increases as anticipated. However, when the duty cycle is increased to 60% and above (up to 100%), the brightness…
Part Number: TPS61165
This is my application circuit.
I have a +3.3V PWM signal applied to J3 (PWM_IN). When I adjust the PWM duty cycle, the signal seen at the C4/R5 junction moves as expected, but instead of holding the 200mV FB pin voltage constant…
Part Number: TPS61165 Hi,
i used a part TPS61165DBVR for lcd backlight control as shown in schematics as below, during testing it is found that applying 10kHz pwm at 50% dutycycle to CTRL pin causes Display back light off and driver not output required…
Part Number: TPS61165 Hi All
I am trying to make this protocol work but to no avail...
