General Description

The SC2820 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power
MOSFETs. It offers a very compact solution to provide a 2A continuous output current over a wide input supply
range, with excellent load and line regulation. ECOT PSM control operation provides very fast transient response
and easy loop design as well as very tight output regulation.
The SC2820 requires a minimal number of readily available, external components and is available in a space saving
SOT23-6 package
