CX8822

The CX8822 is a dual-channel DC-DC step-down (buck) converter IC, commonly used in power management applications. It operates at a 1.5MHz switching frequency, supporting input voltages from 4.5V to 18V and delivering up to 2A per channel with high efficiency (up to 95%).
Key features include:
- Adjustable output voltage (0.925V to 16V).
- Integrated MOSFETs for compact designs.
- Low standby current (~20μA) for power-saving modes.
- Protections like over-current, over-temperature, and under-voltage lockout (UVLO).
Typical applications include consumer electronics, IoT devices, and industrial systems where efficient, dual-output power conversion is needed. Its small SOP-8 package makes it suitable for space-constrained designs.
