Part Number: TPS92640 Hi,
i have an issue with TPS92640.
The BOOT diode failed and created a shortage. Probably the IC is also damaged. A replacement of the diode with DFLS1100 got the IC working again.
Specs: Vin = 48V Vcc = 10.1V
Over an interface a DMX…

Part Number: TPS92640 Hi,
We used a TPS92640 to drive 4 leds in serie. In my last post we have had a problem with the low current start of TPS92640. To solve it, we changed the value from 300nF to 100nF. The TPS92640 starts better but we have problem…
Part Number: TPS92640 Hi
This device is quasi-hysteric control. (on time control) However this device has the valley current control loop also and has the loop compensation.
1) I do not understand how is this device defined the start point of off time…
