Part Number: TPS56221 Other Parts Discussed in Thread: TPS56121 , Hi team
Could you help check if we have P2P alternative of TPS56221 in addition to TPS56121? Thank you.
Part Number: TPS56221 Hi team,
My customer meet some issue on power off, SCH is below:
And below is the power off wave of TPS56221:
Input voltage is 12V, output is 3.3V, load current is 6A, when input power drop to 6.3V, TPS56221 input voltage…
Part Number: TPS56221 Hi,
Is it possible to measure the resistance between Vout and GND without power on TPS56221 EVM?
My customer finished to assemble the board. Before supplying input_power, he measured resistance between Vout and GND to confirm…
Part Number: TPS56221 Hi team,
Our customer pull up PGD pin of TPS56221 to input voltage wrongly(input voltage is 14.5V, pull up resistor is 3.3kohm), we know that the maximum voltage of this pin is 7V, but as customer can`t modify the circuit currently…
Part Number: TPS56221 Hi,
My customer does not use PGOOD pin on TPS56221. On this case, he wants Open(floating) on PGOOD pin. Is it correct? If any issues, please let us know.
Thanks and best regards, M.HATTORI.
Part Number: TPS56221 I am using TPS56221DQPT under the following conditions:
Vin = 12 Vout = 0.85 Fsw = 1 MHz Target Imax = 15 A Target Ipp = 5.2 A
With no load the regulator hits the target voltage. However as soon as I give it more than ~500mA…
Bob,
The voltages for TPS56221 and LM10011 may be the same or different depending on the available voltage rails. TPS56221 can operate from a supply of 4.5 V to 14 V while the supply of LM10011 can be from 2.97 V to 5.5 V. So practically, they can…
Hi John,
Thanks, I will implement.
Please advise If\How the connection of the LM10011 IDAC_OUT to the TPS56221 Feedback affect the selection of of the resistor divider values.

Part Number: TPS56221 Hello,
OCP doesn't work on customer's design as below.
Could you please review the schematic and give some comments?
ILIM resister is 2.7K ohm, customer is expecting OCP at 23A. But it doesn't work at the current, and also…
