MP6006

Wide Input, Primary-Side Regulated, Active-Clamp Flyback Converter

概要

The MP6006 is a wide input voltage (V_IN) range, high-efficiency, active-clamp flyback converter. It is specifically designed for extremely small-sized primary-side regulation (PSR) flyback topologies.

In PSR flyback mode, the MP6006 samples the output voltage (V_OUT) from the SW pin instead of an auxiliary winding, which simplifies transformer design.

The MP6006 integrates two MOSFETs with an active-clamp flyback topology. This saves traditional RCD clamp circuits and provides isolated power solutions with a simple BOM. The compact active-clamp power loop works with the frequency dithering function to provide excellent EMI performance.

The MP6006 adopts line/load regulation compensation techniques to eliminate the leakage inductance's impact on the output regulation.

Protection features include overload protection (OLP), short-circuit protection (SCP), over-voltage protection (OVP), and over-temperature protection (OTP).

The MP6006 is available in a QFN-11 (3mmx3mm) package.
