Preliminary
uP6262
Three-Channel Voltage Console
with I2C Programmable Current DAC in SOT23-8
General Description
Features
The uP6262 is a high precision voltage console consisting
of three sets I2C programmable current DACs. Each current
DAC is capable of sinking 64-step and sourcing 16-step
output current that are programmed by the I2C interface.
The sinking and sourcing current of OUT1 and OUT2 are
programmable for 20x boost respectively.
The uP6262 features soft-jump, easily interfacing with
standard DC/DC converter for voltage console. The uP6262
is available in space-saving SOT23-8 package.
