   产品概述 返回TOPT0p嘉泰姆

The CXMD3260 is a single‐phase, constant‐on‐time, synchron‐  ous PWM controller, which drives N‐channel MOSFETs. The CXMD3260 steps down high voltage to generate low voltage chipset or RAM suppliesin notebook computers. The CXMD3260 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the CXMD3260 provides very high efficiency over light to heavy loads with loading‐ modulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low‐noise requirements. The CXMD3260 is equipped with accurate positive current‐ limit, output under‐voltage, and output over‐voltage prote‐  ctions, perfect for NB applications. The Power‐On‐  Reset function monitors the voltage on VCC to prevent wrong operation during power‐on. The CXMD3260 has a 1ms digital soft‐start and built‐in an integrated output discharge method for soft‐stop. An internal integrated soft‐start ramps up the output voltage with programmable slew rate to reduce the start‐up current. A soft‐stop function actively discharges the output capacitors with controlled reverse inductor current. The CXMD3260 is available in 10pin TDFN 3x3 package.
