Shenzhen Mingjiada Electronics Co., Ltd. offers immediate availability of the MPS NB675GL 24V synchronous buck converter, a high-performance PowerSoC buck solution designed to enhance power supply design for computing and industrial equipment.
NB675GL Product Description
The MPS NB675GL is a high-performance synchronous buck converter belonging to Monolithic Power Systems' (MPS) PowerSoC (Power System-on-Chip) product family. It integrates a high-frequency synchronous rectification buck switch-mode converter (VDDQ), a ±1.5A sink/source LDO (VTT), and a buffered low-noise reference (VTTref). This provides a complete power solution for DDR3, DDR3L, and LPDDR2 memory, optimised for maximum power density.
Key Features Of MPS NB675GL
Wide Input Voltage Range: The NB675GL operates across a broad input voltage range from 5V to 24V, making it suitable for diverse application scenarios.
High Output Current Capability: Its integrated buck converter delivers 10A continuous output current and 12A peak output current, offering excellent load and line regulation performance.
Integrated Functions: The NB675GL incorporates a ±1.5A VTT LDO and a buffered reference voltage source (VTTref). The VTT LDO requires only a single 10μF ceramic capacitor, while VTTref provides high-precision tracking (1% accuracy) of VDDQ/2.
Advanced control and protection: The NB675GL employs a constant on-time (COT) control scheme, delivering fast transient response and simplifying loop compensation. Comprehensive protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), and thermal shutdown protection.
High Efficiency and Switching Frequency: The NB675GL incorporates an internal low RDS(ON) power MOSFET and proprietary switching loss reduction technology, operating at a switching frequency of 500kHz.
Additional Features: The NB675GL also provides internal soft-start, output discharge capability, an internally set under-voltage lockout (UVLO) threshold of 4.5V, and indicates output status via an open-drain Power Good signal.
