Description

SEA01 is a highly integrated solution for SMPS

applications requiring precise voltage and current

regulation.

The device integrates two voltage references, two

op-amps (with open-drain outputs), a low-side

current sensing circuit and an online digital

trimming machine.

The internal reference VrefV, along with one op-

amp, is the core of the voltage control loop.

The internal reference VrefI and the other op-amp

make up the current control loop. The embedded

digital trimming allows the user, through software,

to adjust and permanently store both VrefV and

VrefI internal references during the production test

of the end product, compensating the tolerance of

the external components and the error due to

their discretized values. Redundant OTP gives

the user a second chance to change the values

stored in the non-volatile memory of the IC during

the first trimming process.

This feature allows having the highest end-

product accuracy of voltage and current control

without the use of external discrete components

or manual intervention.
