Part Number: TPS7A78 Hello support team,
My customer asks what is advantage and disadvantage between full bridge and half bridge, could you support?
Full bridge can achieve same load current with smaller cap, what is disadvantage on full bridge?
The simulation has SCIN drooping during the relay event. LDO_IN is unable to maintain headroom to the output, and the LDO_OUT enters dropout. At 0.865 seconds into the simulation the 3.5V UVLO is tripped, turning off the LDO. 3.5V is the "worst case"…
Part Number: TPS7A78 Hi,
My customer using MPS MP100L, if I want provide alternative part. Do you have better suggestion?
TPS7A78 seems only can provide up to 5V output voltage.
Part Number: TPS7A78
The TPS7A78 is used for a load that takes 80mA on average, but also 280mA for peaks of about 500µs. Since the TPS7A78 limits the output current, a 4700µF electrolytic capacitor was placed at the LDO_out. On LDO_in a capacitor…
Part Number: TPS7A78 Hi, another Question regarding TPS7A78:
Is it possible to bridge Charge-Pump? Or asked in another way:
Can I provide external Input-Voltage for VLDOIN and what is the highest voltage I can apply?
I want to use the Voltage of VSCIN…
Part Number: TPS7A78 Hello
we have problems wiith EMC Conducted Emission EN 55014-1 Cond. with TPS7A78.
We have the following component values:
Rs = 330R
Cs = 470nF
CScin = 470uF + 180uF
Csc1 = 1uF
Csc2 = 1uF
CLDOIn = 10uF
To reach compliance we have…
Part Number: TPS7A78 Hello Support team,
Datasheet recommend PFD top resistor divider up to 200k ohm, but, the value on EVM is 2.21Mohm. Does EVM have wrong design? Please clarify it.
Part Number: TPS7A78 Hi friends,
I have experimented with new concepts for the conversion HV-AC/DC (110/230Vac --> 3Vdc) please see> https://www.researchgate.net/publication/357877607_The_Inductor-less_line_supply_for_MCU_-realizations
