Part Number: LP87524B-Q1 Other Parts Discussed in Thread: TPS65273V , TPS65400 , TPS65023 Hi Team,
In on going power supply board design need clarifications on followings,
1. Enable pins,
For 4 Buck only 3 Enable pins are available, How to enable Buck…
Hello.
Would you advise how can buck3 output voltage regulate 2.3V to 1.3V ?
(I need 3.3V, 1.2V, 1.8V and 1.3V)
Should i change R35~R37? or re-program on PMIC?
I read data sheet. However, i don't know exactly.
Can you give me detail solutions?

Part Number: LP87524B-Q1 Other Parts Discussed in Thread: AWR1642 Hi,
For the mmwave radar sensor hardware design, using PMIC LP87524B-Q1, its datasheet recommends connecting an input filter capacitor (10 uF) from VIN_Bx to PGND_Bx. However, the design…
Part Number: LP87524B-Q1 Other Parts Discussed in Thread: IWR1443 ,
Hello
I want to know if the LP87524B-Q comes programmed or do I need to programm it myself?
This the diagram that comes with the IWR1443 Mmwaves, and says that it needs to be progammed…
Part Number: LP87524B-Q1 Hello team,
Customer is asking if the LP87524B recovery automatic after dropping to overvoltage status? When the voltage goes high, the 87524 jump to over voltage protect status. then what happen if the voltage return back to…
Part Number: LP87524B-Q1 Other Parts Discussed in Thread: IWR1843 , IWR6843 Dear TI
now we are use the default register setting for IWR6843 and IWR1843 mmwave sensors .
1 In real application we can online tuning these control register for…
Part Number: LP87524B-Q1 I am using LP87524B to generate and regulate 3 sources. Buck0 is not used and I left Feedback pin floating. The reason for using only 3 and not 4 is the need to enable/disable bucks using the enable pins EN1, EN2, and EN3.
In…
Part Number: LP87524B-Q1 Hello,
Use LP87524B for Radar IC power, during initiate find I2C can't get ACK from LP87524 when ENx is Low.
follow up the below steps, it seems I2C module can't work normal at step 4.
but when pull ENx to high, I2C…
Part Number: LP87524B-Q1 Hello,
Can LP87524B-Q1 be used as four independent buck converters with four separate/different Vin voltages?
Or VIN_B0, VIN_B1, VIN_B2 and VIN_B3 always have to be connected together?
Best regards,
K.Hirano
Part Number: LP87524B-Q1 Hello,
My customer plans to use LP87524B with switching frequency = 10MHz or 20MHz.
Their requirements are as follows.
VIN_B0, VIN_B1, VIN_B2, VIN_B3, VANA = 3.3V
Buck0 = Unused
Buck1 = Unused
Buck2 = 0.9V/2A, ripple voltage…
