Part Number: BQ24640 Tool/software: Hi,
1.We have placed 0.1uF capacitor between PH pin and inductor, at that time we got output 5.8 V but after verifying the datasheet we have updated our schematic and placed the 0.1 uF capacitor in series with diode…
Part Number: BQ24640 Other Parts Discussed in Thread: BQ25756E , BQ25750 Tool/software: Hi
Could you help recommend a suitable product. The customer wants to make a super cap backup power supply.
Specifications are as follows:
1.12VIN / 12VOUT …
Part Number: BQ24640 Tool/software: During some operating conditions, the switching waveform on the gate driver output is abnormal.
At low output voltages and operating currents, the gate driver output for the high side MOSFET has weird sinusoidal pulses…
Part Number: BQ24640 Tool/software: Hi,
In our application we are using bq24640 for super capacitor charging control and we are using its output as our input. Our unit runs on bq24640 output.
1. Input voltage is 24V and output we are operating is…
Part Number: BQ24640 Tool/software: Hi team,
1. May I know how we calculated the value of Cff on the datasheet's typical application circuit? 22pF is required? Are there any other acceptable capacitance?
2. On the EVM schematic, C25 is mounted but…
Part Number: BQ24640 Hello, My customer has some questions as follows. Q1: 7.3.2 Output Current Regulation Regarding the output current regulation, which is the set maximum charging current, peak current, valley current, or average current? Q2: Charge…
Part Number: BQ24640 Tool/software: My customer needs an indication for CC-Mode to know that the supercap final voltage is not yet met.
The Block-Diagram shows this current sink on page 11, and the customer wants to know if this pin always draws this…
