Part Number: TPS61023 Other Parts Discussed in Thread: TPS61022 Hi, This question could pertain to any boost although I'm using TPS61022 and TPS61023 in two designs so might as well focus on them. For a boost, in the situation where the input voltage…

Hello, I upgraded low energy board layout with TPS61023 and TPS610994 converters. Could you check please? Screenshots:
2 first screens are converters area, 3rd is converter…
Part Number: TPS61023 I want a boost converter that takes 3.3V and converts to 300mA@3.6V. It needs to have a low quiescent current of less than 20uA, the load can go as low as 400uA. However when the load has a usb pluged into it the 3.6V output will…
Part Number: TPS61023 Other Parts Discussed in Thread: TPS61022 , TPS61021A Hi
I am working on a project where I need to boost the voltage from a very low voltage source 0.65V (Input) to 5V 1 Amp output, The datasheet suggest the TPS61023 is having a wide…
Hi Kami,
The more detailed design of LM2623 can be found in this app note, LM2623 General Purpose, Boost Converter Circuit
1. At output, a 68 µF or larger output capacitor is recommended to minimize ripple. At input, I think a 22-µF input capacitor…
Part Number: TPS61023 Other Parts Discussed in Thread: TPS61022 Hi,
I need to design 5 V power supply with Li-ion battery. So, input parameters are Vin= 2.8~4.2 V, and output parameters needs to be Vout=5V and Iout=3.5 A. I intend to use TPS61023 with…
Part Number: TPS61023 Other Parts Discussed in Thread: TPS3895 , TPS63061 Hi
Im currently testing the TPS61023 -(in the form of an Adafruit mini boost)
Im designing a pcb to attach to an esp32 - which has an ams117 LDO - max input 15v (cant really replace…
Hi Tom,
In device TPS61023 ,for default condition we are able to set a value up to 13pF for Cff capacitor as shown in image below.
As we increase Cff capacitor value from 1pF to 13pF,phase margin keeps increasing from 68.85 to 118.54 degrees.
As per…
Part Number: TPS61023 Other Parts Discussed in Thread: TPS63060 , , TPS61230A , BQ24179 I tested the part at about 1A output load, 3.5V in (1 LiIon cell) and 5V out. After EN off and on (while load stays on) the part shows only 0.2V output voltage - it does…
