TPS62800: Output Voltage

Part Number: TPS62800

Hi team,

My customer is looking for an ultra low Iq DC/DC. 

The customer would like to change the two output voltage on the fly(dynamically). Is the TPS62800 able to change the output voltage dynamically to another output voltage by changing the VSEL resistor? If it's not allowed, could you tell me the recommended device?

Vin : Li-Ion 1cell

Vout : 0.5V/0.65V

Iout : TBD, but it should be less than 1A.

Package : Small size like CSP

Regards,

Yamaguchi

  • Hi Yamaguchi,

    In TPS62800, the VSEL pin is set at startup and cannot be changed dynamically later. 

    My suggestion would be TPS628610 in a DSBGA package (one of our latest devices which is in pre-production stage). The device has I2C interface and a dedicated VSEL pin, by which the output voltage is adjusted during operation. Please have a look at the datasheet: http://www.ti.com/product/TPS62861
