Resolved! Using MPP on stwlc38

Is it possible to use a Qi2 rx coil with magnetic array on a stwlc38 design? The goal is to use a Qi2 charger and reap the benefits of magnetic alignment and 15W charging while still being on the Qi1.3 standard of the stwlc38.

Viper06LS shuts down over 520 VDC Input Voltage

Hello,I use the Viper06LS in the Buck Converter topology.The input voltage can vary between 100V and 530VDC. The output voltage is regulated to 10 V. (See "Viper_circuit"!)Unfortunately, a problem arises when the input voltage increases to approx. 52...

L6235

Hi I want to use a L6235 to control a BLDC motor, but do not have a micro to control the loop.  Micro not an option. The are two options I have is to use an integrator as per datasheet or use app note DT0001 mention using the Tacho output and the FWD...

VNF1048F Reverse current behavior

Hello,I am planning to use the VNF1048F as a eFuse for my current project.From the datasheet it is not clear to me which is the behavior of the VNF1048F in case of reverse current.Does it automatically close the MOSFETs (to avoid diode conduction), d...

SPV1050 MPPT resistor

There is confusion about resistor values on input voltage divider.According to datasheet voltage on MPP pin should be lower than 2.1 V (Vuvp - 0.1V)In application note AN4397 you used UVP set by resistors R4, R5, R6? Which value should be used?
