onsemi CAT3644HV3-GT2, a 4-output DC-DC regulator, utilizes a switched capacitor (charge pump) topology for efficient LED driving. This device provides multi-step dimming control with a per-channel output current of 25mA. Operating with a supply voltage range of 2.5V to 5.5V, it delivers a regulated output voltage of up to 7V. The internal switch capability and a switching frequency between 1MHz and 1.3MHz contribute to its performance. Packaged in a 16-TQFN (3x3) with an exposed pad, the CAT3644HV3-GT2 is suitable for surface mounting and is supplied on tape and reel. This component is commonly employed in backlight applications across various electronic devices.
