Monolithic Power Systems NB682GD
The NB682 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with 2-Bit VID, especially designed for IMVP8 applications—VCCIO, PRIMCORE, V1.0A, EDRAM, and EOPIO, as well as other POLs (1.8V/2.5V/3.3V). It offers a very compact solution to achieve a 3A continuous output current and a 4A peak output current over a wide input supply range. The NB682 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.| Part No. | NB682GD |

DESCRIPTION
NOT RECOMMENDED FOR NEW DESIGNS, REFER TO NB695FEATURES
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. NB682 provides both a low-power mode for power-loss saving during the low-power state and ultrasonic mode to avoid audible noise. Full protection features include OC Limit, OVP, UVP, and thermal shutdown (TSD).● Wide 4.5V to 28V Operating Input Range
