产品概述 返回TOP
The CXSD62107 is a single-phase, constant-on-time, synchronous PWM controller, which drives N-channel MOSFETs. The CXSD62107 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The CXSD62107 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the CXSD62107 provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements. The CXSD62107 is equipped with accurate positive currentlimit, output under-voltage, and output over-voltage protections, perfect for NB applications. The Power-OnReset function monitors the voltage on VCC and PVCC to prevent wrong operation during power-on. The CXSD62107 has a 1.2ms digital soft-start and built-in an integrated output discharge device 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. The CXSD62107 is available in 16pin TQFN package respectively.
