Part Number: TPS61087 Hi TI ENG team
I want to know how to calculate inductor current spec.
My design spec is
1) Vin=+3.0V~+4.2V, => li-ion battery 1-cell
2) Vout = +7.5V
3) Iout = 0.3A
4) Fsw=1.2MHz
5) n=0.9(90%), ripple=0.35(35%)
I calculated inductor…
Part Number: TPS61087 Tool/software: WEBENCH® Design Tools Dear
I designed SCH with TPS61087 . when the load is light, it can work normally, but when I increase load , it can't Boost . can you give me some advices?
I am looking forward!

Dear all
I would like to ask questions about LED PWM dimming using TPS61087.
Our customer is trying to do LED dimming by inputting a 200Hz pulse signal to the EN pin as in the following…
Part Number: TPS61087 Hello team,
To set output voltage, Datasheet recommend like below,
The output voltage is set by an external resistor divider. Typically, a minimum current of 50 μA flowing through the feedback divider gives good accuracy and noise…
Dear Helen and Brigitte
Thank you for your reply.
There are additional things to check. When the circuit is confirmed, it is a circuit in which the operational amplifier is connected to the wiring of the FB terminal as shown in the figure below. The reason…
Part Number: TPS61087-Q1 Hi Team,
datasheet mentioned, Cin need to be 2x10uf or 1x22uf. Just want to check if 1x10uf is OK. To my understanding, it just affect input ripple. Thanks.
