APW7209 Datasheet (ANPEC) - Step-Up Converter

APW7209, Step-Up Converter

The APW7209 is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 10 white LEDs in series.

The series connection allows the LED current to be identical for uniform brightness.

Its low on-resistance of NFET and low feedback voltage reduce power loss and achieve
