Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
We are currently using the ST1PS02BQTR for powering a compact main board with BT connectivity (STM32WB5MMG), an IMU, and other ancillary blocks (LEDs, charge pump for LEDs, passives). The system is powered through two AAA batteries connected in serie...
Hello everyone, to simulate wireless charging of a smartphone (I want to achieve 5W transmission to the load), I need to use an electronic load and add the load step by step. Since the wireless charging system cannot immediately absorb high current, ...
Hello, I have designed and assembled a SMPS based on the EVAL-STCH03-45W evaluation board. What I have noticed, is that the power supply is outputting 1 Hz pulses with short buzzing sounds. These symptoms usually mean the hiccup mode is activated. Ho...
I am evaluating a PFC with the EVL4986-350W evaluation board.To be able to use Boost coils without the extra winding I want to supply the VCC voltage from a buck converter connected to the output voltage. The voltage from the buck is 17V.I have tried...
I have a PowerSTEP01 that is behaving unexpectedly when I send the ResetDevice command.If I send it when my system starts then everything is ok when I check the STATUS register.However, if I send ResetDevice after the motor has been moved (sequence e...
Dear allI use an STEVAL-ISV019V1 (Boost Mode) with a KXOB25-05X3F PV cell.When I connect a 330mF supercap to BATT, working at low light (200Lux) Store is being charged withing 30s. Not the SPV1050 tries to switch to the Supercap and restarts because ...
Hi everyone, I'm just starting in this field and I'm designing my first product. I'm designing a device that will use the L293D microchip and I'd like clarification on the following issues:1) There is a maximum value for the high voltage input curren...
According to datasheet, L6924D has the possibility to set a maximum charging time, defined according to the capacitor connected in TPRG pin. But what should be done if the maximum charging time limit is undesirable? Can I short TPRG to GND to achieve...
Respected Sir/Ma'am, I'm designing 2KW SMPS from reference schematics design of "STEVAL-ISA172V2: 2 KW fully digital AC-DC power supply (D-SMPS) evaluation board". I've not faced any obstacle in designing schematics ...
Hello ST Community,I'm currently working on simulating a flyback topology using VIPERGaN100 and SR1001 for synchronous rectification control in eDsim. However, I've encountered an issue as the SRK1001 synchronous rectification controller is not avail...
