Power management

Is it possible to connect multiple SPV1040 in series-parallel or parallel-series?

I have an application with multiple solar cells (1.5A/0.57V @MPP). Since the cells are not going to get uniform lighting, I cannot connect them in series and must recurr to a distributed maximum power point(s) tracking system. The idea was to employ ...

STEVAL-EDUKIT01 inverted pendulum equations

I came across the STEVAL-EDUKIT01 system and I'm trying to follow the manual downloadable from the ST website but I already have difficulty understanding the equations that govern the inverse pendulum presented in appendix D on page 143 of this manua...

We design a buck converter on L4971D and expected output 3.3V but only get 0.65V with 48VDC Input.we tune OSC pin resistor up to 5K then output is 3.3V but when input decreases below 35VDC then output again 0.65 to 1.2V.

R3 = zero ohm C5, R4 = DNM

I'm looking for SCT070W120G3-4A Datasheet.

SPV1050 - 100mV on BATT pin and no output on LDO2?

Hi! I'm working on a project using SPV1050. The configuration and schematic for my device is as on the schematic below. I'm providing 4.3V on line PV+ (pin20), yet I have only 100mV (not rising) on BATT pin and absolutely no output on LDO2 pin. Why c...

TVS uni-directional diode

A TVS diode labelled as SJ 5C.What would be the value of the TVS diode? Thanks

I have a STEVAL-POE001V1 development board. connected to a Planet FSD-10088hp switch https://www.planet.com.tw/en/product/fsd-1008hp. I have removed R15. LEDs D2 and D13 blink on and off. Do you know why this is?

Why does the LD39050 have a maximum capacitance value?

We have been seeing some intermittent failures of the LD39050 in our products. I can't see anything wrong with the design other than the output capacitance. The datasheet specifies a maximum of 22uF for stability, but our design has approx 30uF on th...

Hi, I plan to use the TSC212IYCT for 0-1250nA current measurement. Is there any tools I can use to simulate the circuit before I build it?

I only saw there are few options for current sensing using your tool and I cannot set the current below 6A. I need to make a current shunt to measure 0-2000nA
