Description
General part information
EVLCMB1-90WADP Series
The EVLCMB1-90WADP demonstration board is a 19 V - 90 W converter, tailored for the typical specification of an ac-dc adapter for laptops and notebooks, with a wide input mains range and very low power consumption under light-load.
The architecture is based on a two-stage approach: a front-end transition mode PFC pre-regulator and a downstream LLC resonant half-bridge converter; the PFC and LLC are both integrated in the STCMB1 combo IC.
The PFC section uses a proprietary constant on-time control methodology that does not require a sinusoidal input reference, thereby reducing the system cost and external component count. The LLC section is based on a proprietary time shift control method with simple compensation; this improves the dynamic behavior and input ripple rejection resulting in a cleaner output voltage bringing advantages to the circuitry placed to the SMPS secondary side.
