Hello all,
I am facing a problem with the TSP61235PWRLT boost converter IC. I am getting desired voltage (5.15v) on the output side of boost converter but it includes switching frequency. Even after connecting appropriate components I am getting switching frequency (1MHz) on the output side.
Please consider the following schematic and layout for review.
R52 “0 Ohm” resistor is kept DNP.
Following are the part number of capacitor and inductor used in boost converter.
- Inductor
- 1uH – SRN6045TA-1R0Y
- Capacitor
- 150uF – TSPD157K010S0100 (Both on input and output side)
- 0.1uF - CC0402KRX7R7BB104 (Both on input and output side)
I have attached output images of boost converter for your reference.
The peak to peak voltage is 178mv and frequency is 911.58 KHz.
Following are the few images of output waveform of boost converter.
