MP2329 24V, 6.5A, Low I , Q Synchronous, Buck Converter The Future of Analog IC Technology DESCRIPTION FEATURES Wide 4.5V to 24V Operating Input Range The MP2329 is a fully integrated, high- 105 A Low Quiescent Current frequency, synchronous, rectified, step-down, 6.5A Continuous Output Current switch-mode converter. The MP2329 offers a 7.5A Peak Output Current super-compact solution that achieves 6.5A of continuous output current and 7.5A of peak Adaptive Constant-On-Time (COT) Control output current over a wide input supply range. for Fast Transient DC Auto-Tune Loop The MP2329 operates at high efficiency over a Low R Internal Power MOSFETs DS(ON) wide output current load range based on MPSs Proprietary Switching Loss Reduction proprietary switching loss reduction technique Technique and internal low R power MOSFETs. DS(ON) Power Good (PG) Indication Adaptive constant-on-time (COT) control mode Fixed 700kHz Switching Frequency provides fast transient response and eases loop Stable with POSCAP and Ceramic stabilization. The DC auto-tune loop combined Capacitors with the remote differential sense provides good Internal Soft Start (SS) load and line regulation. Output Discharge Full protection features include over-current OCP, OVP, UVP, and Thermal Shutdown protection (OCP), over-voltage protection with Auto-Retry (OVP), under-voltage protection (UVP), and Available in a QFN-11 (2mmx2mm) thermal shutdown. Package The MPL-AL6050 Inductor Series Matches The converter requires a minimal number of Best Performance external components and is available in a QFN- 11 (2mmx2mm) package.
