ADD8754 is a step-up switching regulator with 2 A power switch
The ADD8754 integrates a high‑frequency step‑up switching regulator, a 2 A internal power switch, a logic‑level LDO regulator, a Vcom amplifier capable of 300 mA, and a gate‑pulse modulator for TFT LCD panel driving. It supports selectable switching frequencies of 650 kHz or 1.2 MHz and provides an adjustable output up to 20 V.
The device is offered in a 24‑lead Pb‑free LFCSP package, operates over an industrial temperature range (‑40 °C to +85 °C), and includes protection features such as UVLO, thermal shutdown, and ESD sensitivity. Pin configurations and functional block diagrams are provided for system integration.
