Product Detail

The NB669 is a fully integrated high frequency synchronous rectified step-down switch mode converter with 5V fixed output voltage. It offers very compact solution to achieve 6A continuous output current and 9A peak output current over a wide input supply range with excellent load and line regulation. The NB669 operates at high efficiency over a wide output current load range. Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization. Under voltage lockout is internally set as 4.15 V. An open drain power good signal indicates the output is within its nominal voltage range. NB669 also provides a 5V LDO, which can be used to power the external peripheries, such as the keyboard controller in the laptop computer. A 300kHz CLK is also available; its output can be used to drive an external charge pump, generating gate drive voltage for the load switches without reducing the main converter? efficiency. Full protection features include OCP, OVP, UVP and thermal shut down. The converter requires minimum number of external components and is available in QFN16 (3mmx3mm) package.
