Part Number: TPS92515 Hello TI support,
We intend to use TPS92515 in an constant current application with load of 156mH & 50 ohms (coil).
1. Can we use IADJ pin to set constant current of 250mA ? Or that pin can only be used to control max current…
Part Number: TPS92515-Q1 Other Parts Discussed in Thread: TPS92515HV What is the maximum switching frequency of the TPS92515HV? Assuming maximum output current of 2A.
Part Number: TPS92515-Q1 Hi team,
Looking at the calculations for Roff in the datasheet and the calculator tool, I had a few questions regarding the Roff sizing.
If we have a fixed input voltage, should we be sizing our Roff for our maximum or minimum…
Hi, Kazuya,
If PWM1 (external shunt FET) control, it would be within ~ns to tens ns, depending on PWM1 and shunt FET on speed.
If TPS92515 PWM pin used, inductor current ramps up from 0 until regulated current. Thus, ramping up speed related to inductance…
Hi Xiao,
1, The toff and delta Ip-p are depended the VLED. I wanted to know VLED to compare between the theory and the fact. The currently, to do the calibration, I use the multimeter to know Imax so I don't need VLED information any more.
2, I found…
Part Number: TPS92515 Hi Experts,
We are designing a circuit to control LED brightness and blink frequency. Brightness control comes with most of the chip by default but controlling blink frequency is not available in any of the chip we searched so far…

Part Number: TPS92515-Q1 Other Parts Discussed in Thread: TPS92515 Hi team,
i notice this link, there is a limit condition for the PWM=30Hz ,but the duty cycle is a concern.
