NCP6922CBMTTXG

NCP6922CBMTTXG Description

The NCP6922CBMTTXG from onsemi is a highly integrated quad-output power management IC (PMIC) combining two high-efficiency 800mA buck converters and two low-noise 150mA linear regulators. Designed for surface-mount applications, it operates from a 2.3V to 5.5V input voltage range, making it suitable for battery-powered and portable devices. With a 3MHz switching frequency, it minimizes external component size while maintaining high efficiency. This PMIC is ROHS3 compliant and REACH unaffected, ensuring environmental and regulatory compliance. However, it is marked as obsolete, so alternative solutions should be considered for new designs.

NCP6922CBMTTXG Features

• Quad Outputs: Two 800mA buck converters (0.6V–3.3V adjustable) and two 150mA LDOs (1V–3.3V adjustable).
• High Efficiency: 3MHz switching frequency reduces inductor size and PCB footprint.
• Wide Input Range: Supports 2.3V–5.5V, ideal for Li-ion, Li-poly, or USB-powered systems.
• Compact Design: Small form factor with Tape & Reel (TR) packaging, suitable for space-constrained applications.
• No Sequencer/Supervisor: Simplifies design but requires external sequencing if needed.
• Moisture Sensitivity Level (MSL) 1: Suitable for extended storage and handling.

NCP6922CBMTTXG Applications

• Portable Electronics: Smartphones, tablets, and wearables benefit from its compact power management.
• IoT Devices: Low-power sensors and wireless modules requiring multiple regulated voltages.
• Embedded Systems: Industrial and consumer applications needing efficient, multi-rail power.
• Battery-Powered Devices: Efficient buck converters extend battery life in handheld equipment.

Conclusion of NCP6922CBMTTXG

The NCP6922CBMTTXG offers a balanced mix of efficiency, integration, and flexibility for multi-rail power systems. Its high-frequency switching and compact design make it ideal for portable and space-sensitive applications. However, its obsolete status means engineers should evaluate newer alternatives for long-term availability. For legacy systems or specific designs, it remains a viable choice for efficient, multi-output power management.
