Hi, Fergus:
For some reason, I didn't receive the P MOSFET yesterday and couldn't test it.
Yesterday I sent you a blank schematic, I don't why. resending....
In the new schematic, I move the AS431 to the output side. You can see how tough…
Part Number: TPS61288 Hi,
I need your help desperately.
With E2E help, I built a prototype to test, see attached schematic. it consists of 2 portions: TPS61288 boost circuit and a Vin clamp/cut-off circuit (D1,Q1,Q2, D3).
Design goal: Battery voltage 8V…
Part Number: TPS61288 Hello please let me know the maximum output current For tps61288
Vin=3 volts (lithium ion battery)
at two output adjustable values
Vout 1=5V
Vout 2=12V
and please also let me know its thermal safe value As well for smooth operation…
Hi, Fergus:
I order TPS61288 sample, it's too small. I can't use breadboard to build prototype for verification. I prefer SOIC or small pitch SOC (I can solder wires to the pins and use copper foil for heat dissipating). I search TI website, only find…
Part Number: TPS61288 Queries are as listed below:
Do we need to short AGND & PGND?
a) If yes short directly or use Ferrite Bead in series to join them ?
b) If no, then how to route AGND & PGND with a 2-layer board of 1 ounce on each side ?
c…
Part Number: TPS61288 Other Parts Discussed in Thread: TPS61376 , TPS61170
Please suggest any changes required.
input - 9-15V
output - 18V at 4-10ma
Additionally, Is it possible to reduce the inductor size?
Part Number: TPS61288 Hello,
is it possible to deliver a little current out of the internal 5V LDO (VCC pin) for some other circuitry?
Thanks in advance for any information
Part Number: TPS61288 Other Parts Discussed in Thread: LMR62014 , , TPS61046 Hello,
I currently use a TPS61288EVM-064 in standard configuration and an output voltage of 15V. I connected 4700uF directly to the output of the Booster. As soon the voltage…
Part Number: TPS61288 Hi team,
Customer notice Vout is +3.65V with Vin=+4V, EN pin=LOW. I think output is 0V because TPS61288 is Synchronous Rectification. Is it a correct behavior?

Part Number: TPS61288 Hi Sir,
may we understand this SOO mode,
under normal circumstance, the ripple of PFM is large than PWM? right.
but because TPS61288 has SOO mode, it can make PFM ripple smaller than PWM? under light load.
