APW7136A Datasheet (Anpec) - Step-Up Converter

APW7136A, Step-Up Converter

The APW7136A/B/C is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 8 white LEDs in series.

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

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