General Description

The ASP9330 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal

power MOSFETs. It offers a very compact solution to provide a 3A 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 ASP9330 requires a minimal number of readily available, external components and is available in a space

saving ESOP8 package.
