SLVSGG8 November 2023 TPS6287B10 , TPS6287B25
PRODMIX
The TPS6287Bx has an overvoltage lockout function that disables the DC/DC converter if the supply voltage is too high for correct operation. The positive-going threshold of the OVLO function is 6.3 V (typical). If the supply voltage increases above this value, the device stops switching and, if DISCHEN = 1 in the CONTROL1 register, turns on the output discharge.
The device automatically starts switching again – it begins a new soft-start sequence – when the supply voltage falls below 6.2 V (typical).
