Part Number: TPS62147 Hi,
how does the TPS62147 behave, when a chip internal error occurs, regarding potential shorts from Vin, Mode, Enable, Fsel to GND?
Are there functional safety documents?
Part Number: TPS62147 Tool/software: Hi Im using TPS62147, Vin = 12V Vout <=> Variable tracking voltage on SS/TR pin (1-10V). 1:1 ratio. e.a I want the Vout tracks the SS/TR voltage, with ratio 1:1. Result: It's stuck @ Vout = 9.6V, when changing the…
Part Number: TPS62147 Dear TI support team,
I have a question about TPS62147RGXR(in case of VIN=5V, FSEL=high(2.5MHz)).
How much is variable of Fsw expected depending on individual difference or etc. if output current is fixed value?
I would like…
Part Number: TPS62147 Hi,
My customer is designing the following:
Device : TPS62147 @ 1.25MHz SW-Freq
Inductor : 2.2uH
Input Voltage : 5V
Output Voltage / Current : 1.0V @ 0.9A
Output capacitance : C1:44uF near inductor and C2:491uF(total…
Part Number: TPS62147 Hi,
I want to modify the output of the TPS62147RGXR so that it can withstand 100V externally applied like this:
Is this circuit still stable for all possible output voltages and the LC filter combinations as given in the datasheet…
Part Number: TPS62147 Other Parts Discussed in Thread: TPS61196 , FROM CUSTOMER: Our LCD driver PCB is using a this part for 10V power to the LCD, and a TPS61196 LED driver to power the backlight. We are experiencing an issue that is looking more and…
Part Number: TPS62147 Hi team,
My customer will use TPS62147 with Vin=12V, Vout=1.8V, fsw=1.25MHz. But Figure 74 shows switching frequency variation looks large around Vin=12V when Vout=1.8V.
Why variation of fsw at below circled point is relatively…
Part Number: TPS62147 Hi team,
My customer will use TPS62147 and he is asking question. As for equation(12), what does "100ns(2.5MHz)/200ns(1.25MHz)" mean?
It looks like on time. But it should be equation(1) or (2). Why 100ns/200ns(25% of duty cycle…
