APW7209 - Step-Up Converter

General Description

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.

Key Features

  • Wide Input Voltage from 2.5V to 6V 0.3V Reference Voltage Fixed 1MHz Switching Frequency High Efficiency up to 88% 100Hz to 200kHz PWM Brightness Control Frequency Open-LED Protection Under-Voltage Lockout Protection Over-Temperature Protection.
