  • Hello ,
    I looked through your customer specifications and TPS65175 has VGH range of up to 34V and your customer specification for this parameter is 36V typical and 38V maximum, so it will not meet the requirements for gate driver VGH supply. TPS65170 negative charge pump also goes to a minimum of -8.1V which is higher than -10.4V specified in customer specification. Other integrated LCD bias/level shifter devices seem to not meet all the specifications.
    I would suggest for you to meet with your customer and interactively use the product selection filter for LCD bias solutions (link below) so that customer can make appropriate compromises to select a suitable device in real time.
