Part Number: TPS61194-Q1 Other Parts Discussed in Thread: TPS61194 Tool/software: When our products do transient undervoltage (input voltage drop to 6V) test, it is found that the PWM (duty cycle is 60%) frequency at 1KHz backlight flicker, not at 20KHz…
Part Number: TPS61194 Tool/software: My Hardware setting : VDDIO/EN is pulled high by CPU GPIO pin with 820KOhm series resistor
Case1: VIN=19V，TPS61194 is operating and functional, as picture below, VDDIO/EN pin is pulled up to 2.29V to start TPS61194…
Part Number: TPS61194 Tool/software: Hi
The customer wants to confirm whether TPS61194PWPR can connect OUT1~4 to the negative terminal of Panel Backlight? Because the Panel requires nearly 400mA
Part Number: TPS61194 Tool/software: The data sheet for the TPS61194 shows the following:
When the VDDIO/EN signal is set to about 2 to 20us L and then returned to H, the fault signal is restored. Also, if the condition for detecting LED short state…
Part Number: TPS61194-Q1 Other Parts Discussed in Thread: TPS61194 , LMR14020-Q1 Hi,
The customer experienced a cluster backlighting issue.
Issue: LCD backlight does not turn on when OFF -> ON at low temperature ~ -15℃.
In normal case, 27V voltage…
Part Number: TPS61194-Q1 Hi expert,
Could you please help to explain why there are two different package layouts on datasheet page 34 and page 36? Which one should we follow? Thanks.

Part Number: TPS61194 The TPS61194 operates at 1300 kHz. Input voltage 12 volts, output 21 volts, output current 380 ma. I deliberately used 2 and not 3 capacitors of 10 microfarads.
I have a problem when the TPS61194 stops working after a while and…
Part Number: TPS61194 hi,
We use the TPS61194 to drive the LCD of the cars' dashboard . Sometimes when the users start the engine, the voltage of the supply for dashboad decrease baddly , so the the TPS61194 can't boost and the output is near the input…
Part Number: TPS61194 Hi team
Could you help give the recommended "ambient temperature range" for TPS61194?
D/S only shows "–40 to 125 " under "Absolute Maximum Ratings" but the customer wants to know the recommended ambient temperature range.
Part Number: TPS61194-Q1 The SW frequency is 2Mhz. When the PWM is 19K and the duty cycle is 7.5%, Output capacotr have sound noise.
But if I increase the duty cycle by more than 10%, the sound noise disappears;
Why? Can you explain this phenomenon…
