Hi,
The control loops of both the LM26420 and TPS62442 don't support the output rails to be combined. You would need to choose a 4A part like TPS62865.

Part Number: TPS62868 Other Parts Discussed in Thread: TPSM82864A , TPS62865 Hi,
According to datasheet, output voltage can be selected between two output voltage registers by the VID pin.
For TPS628680ARQY, the VSET/VID pin is connected to external resistor…
Hi Chris,
Thank you for the answer and suggestion. Yes, TPS54519 does meets our requirements. Unfortunately TPS62865/7 do not meet our requirements of either current output or HS-FET current limit.
Hi Nan,
Vout register 1 is loaded with the voltage from the VSET resistor. Vout register 2 always has 0.9V. You can change both of these voltages with I2C and use the VID function to switch between them during operation (if you want to).
Yes, you can…
Hello Ella,
The other possible options are TPS62826/7 or TPS62865. Both ICs offer lower on-state resistance, so expect >1% higher efficiency than TLV62585. TPS62865 is in a bigger package than TPS62826/7, and it will result to better thermal performance…
Hi Marvin,
After startup, the device regulates to the voltage in the Vout 1 or 2 registers. Section 8.4.4 explains how the VID pin chooses between Vout 1 and Vout 2.
If you don't use the I2C bus, then the device will only output those voltages. Changing…
Other Parts Discussed in Thread: TPS62864 , TPS62800 , TPS62865 What are the advantages of multi-function pins and how do I best design my application using multi-function pins (VSET/VID for TPS62864/6/8/9, VSET/MODE for TPS62865/7 and VSEL/MODE for TPS62800…
Hi Aaron,
Both TPS53310 and TPS53311 are from the same die and p2p compatible.
For new designs, I would like to propose newer devices like TPS62865/7 .

Hello Suliman,
I would recommend the same thing here as the thread you opened with TPS62865.

Part Number: TPS566231 Other Parts Discussed in Thread: TPSM82823 , TPS62865 Hi,
We are using TPS566231 on our custom board to generate a 5V with up to 4.5A current. this 5.0V buck feed other DC-DC convertors likeTPS62865 and TPSM82823 to generate more…
