The CXSD62175 is a 8A, synchronous, step-down converter with integrated 12mW N-channel High-Side MOSFET and 12mW Low-Side MOSFET. The CXSD62175 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The CXSD62175 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the CXSD62175 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 CXSD62175 is equipped with accurate current-limit, output under-voltage, and output over-voltage protections, perfect for NB applications. A Power-On-Reset function monitors the voltage on VPVCC and VCC to prevent wrong operation during power-on. The CXSD62175 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 CXSD62175 is available in TQFN5x6-28 (Power PAK) package.
