产品概述 返回TOP
proprietary Instant-PWM™ fast-response, constant-on-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near constant operating frequency over line, load and output voltage ranges. This control method provides stable operation without complex compensation and even with low ESR ceramic capacitors.The CXSD62547 is a high efficiency synchronous step-down DC/DC regulator featuring internal power and synchronous rectifier switches capable of delivering 6A of continuous output current and up to 12A peak output current over a wide input voltage range of 4V to 28V.Internal 40mΩ power and 20mΩ synchronous rectifier switches provide excellent efficiency over a range of applications, especially for low output voltages and low duty cycles. Cycle-by-cycle current limit, input under voltage lock-out, internal soft-start, output under- and over-voltage protection, and thermal shutdown provide safe operation in all operating conditions.The CXSD62547 is available in a compact QFN3X3-12 package.
