LED2001 Smoked with set to 4A output
Dear Support,I have a design which works fine even drive it full PWM with 0.025 ohm (4A max current). we need to control the backflow current so added a diode on the power supply path. the schematic is attached. C169 and C170 not installed. it works...

Thermal resistance information ST6710
Hello,I need some information on the thermal resistance Rthja and Rthjc of the STM6710 (package SOT23-6L). Could you please send some technical information like a datasheet which we can forward to certification authority?I often miss this information...
L6482 current control parameters
Hi,I am concerning about the L6482 current control parameters that are explained in the AN4158.I assume that tSW, tON_MIN, tOFF_MIN, tOFF_FAST, tFAST_STEP reflect the relevant registers. So:1. Peak current control with auto adjusted decay: - tOFF: th...
Resolved! WBC2TX50 board does not go past FSM_PRE_PING_STATE
I have a WBC2TX50 eval board along with a STEVAL-WLC98RX for testing Qi powe transfer. When I try to make the transfer, the WBC2TX50 board does not go past FSM_PRE_PING_STATE, either with the WLC98RX or with a phone, both of which work with a standar...
Vipergan50TR, switching frequency
Dear ST office, I have a project with the chip Vipergan50TR.We need the output voltage of 20V/0.2A, -20V/0.2A, 7V/1.5A. We plan to let the vipergan chip control 20V channel. I tried your online design tool for AC/DC. When i typed in output voltage ...
