The NB680A is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with a fixed 3.

Product Detail

The NB680A is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with a fixed 3.36V Vout and low-power mode voltage scaling. It offers a very compact solution to achieve an 8A continuous output current and a 10A peak output current over a wide input supply range with excellent load and line regulation. The NB680A operates at high efficiency over a wide output current load range based on MPS proprietary switching loss reduction technology and internal low Ron power MOSFETs. Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization. The DC auto-tune loop provides good load and line regulation. The NB680A provides a fixed 3.3V LDO, which can be used to power the external peripheries, such as the keyboard controller in laptops. Also, a 250kHz CLK is available on the NB680A. 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 OC limit, OVP, UVP, and thermal shutdown. NB680A requires a minimum number of external components and is available in a QFN-12 2mm x 3mm package.
