WL700 SMD IC Transceiver IC SOP-8 RF WIRELESS WL700

Product Overview: The AP3019A is an inductor-based DC/DC step-up (boost) converter specifically designed to drive up to eight white LEDs in series for backlight applications. It utilizes a constant 1.2 MHz PWM control scheme, allowing for the use of tiny external components (such as a 1mm tall inductor and 0.22µF output capacitor) to save space. It also features an integrated Schottky diode, reducing the need for additional external components, and includes output over-voltage protection to clamp the voltage if an LED fails or other abnormal conditions occur.
