What are the key specifications of the HX4002?

It supports up to 250mA output current, features a 1.2MHz switching frequency, includes soft-start and short-circuit protection, and operates with <1µA shutdown current.

What should engineers review before using the HX4002?

Engineers should ensure the use of low ESR (<0.1Ω) ceramic capacitors (10µF or greater) for input and output, and at least 2.2µF for the flying capacitor. The EN pin must be driven with a valid logic level and never left floating.

What is the pinout of HX4002-MFC?

Use the HX4002-MFC datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about HX4002-MFC pinout to locate pins, power rails, and interface signals before layout.
