Part Number: TPS2812 Other Parts Discussed in Thread: UCC27444 Tool/software: Hi support team,
Is there a minimum specification for "Positive-going input threshold voltage" when VCC=5V?

Figure 1
How are the RC parameters of the two snubber circuits (R20, C16, R21, C17) of the push-pull converter in Figure 1 taken? How to calculate the power consumption of R in the snubber circuit?
In addition…
Part Number: UCC2808-1 Other Parts Discussed in Thread: TPS2811 , TPS2812 , LM5030 , Tool/software: Hello,
I'm looking for the LTspice files for the components UCC2808-1D and TPS2812D, it can be a .lib or .cir file. I'd like to simulate a DC/DC 'push-pull…
Part Number: TPS2812 Other Parts Discussed in Thread: TPS2816 , I am using this IC to drive a MOSFET. When I check the datasheet there is a application circuit. But this circuit does not use the internal voltage regulator. I was wonder if someone can provide…
Part Number: TPS2812 Other Parts Discussed in Thread: UCC27524A
Hi all Would you mind if we ask TPS2812? We consider the formula for the temperature rise as follows; -Total power dissipation : (Ig^2 × Rds) + (Vcc × Icc) -θja × Total power…
David,
When the TPS2812 input is ~30V, you are dropping V_LDO=30 V-11.4 V=18.6 V. The UCC2808A-2 requires I_q=2 mA so the TPS2812 is dissipating ~37 mW just due to biasing the UCC2808A-2. You need to calculate the additional power dissipated in the TPS2812…
Hi,
When you say disconnect from gate, can you specifically indicate how do your disconnect - disconnect from TPS2812 from UC2808, or disconnect TPS2812 from MOSFETs?
Part Number: UCC27524 Other Parts Discussed in Thread: TPS2812 Hi,
we promoted UCC27524 to replace IR4427 on the customer's boost circuit to drive the low side IGBT.
With IR4427 they can pass the EMC test but not with our UCC27524. They've adjusted…
Hello Saurabh,
The TPS2812 regulator can be used to extend the input voltage range of the available bias. The usable VCC range is 4V to 14V. The regulator can accept input voltage up to 40V and provide 11.5V output to be connected to VDD.
The TPS2812…
